We implement a new `Element` trait which allows for more complex output
to be drawn, such as vertical and horizontal stacks.
We adapt `Table` to work within this system.
We refresh the output of `rad patch show` to use these new tools.
For display purposes in the web client, we add with this commit the
some needed properties to the revisions in the patch endpoint.

It's not a good idea to have fallible operations run after `FetchOk`
is received, since there's no easy way to communicate the error
to the remote at that point. What would then happen is that the fetch
just "hangs", since nothing is there to cancel it.
Hence, we compute namespaces earlier in the process, and store the
namespaces in the session. If there is a failure, the fetch is
never initiated.
The Reaction type needs to ensure that the `char` stored for its value
meets certain requirements -- via its `new` constructor.
To ensure Reaction is always constructed correctly, the `pub` accessor
is removed, and the Deserialize implementation is implemented by hand
-- as opposed to using derive.

If Ops::try_from fails in from_history then it means that some
operations failed to be parsed.
If this happens, then a warning should be logged so that these failure
cases can be more easily traced.

Periodically, make sure we try to fetch inventory that is tracked
but missing from local storage.
We decide not to fetch immediately on `TrackRepo`, as this limits
the command's flexibility. For example, when `rad clone` is used,
we want to be able to fetch manually after tracking.
By introducing a small limitation: only allowing entries in the change
graph to be addressable, instead of individual operations; we
drastically simplify the CRDT implementation.
There are four advantages:
1. Op ids are just regular SHA-1s
2. There's no need for relative IDs, ops never refer to other ops within the
same commit
3. There's no need for a nonce, since commits can't collide, and neither can op IDs
4. `OpId` can just be an alias of `EntryId`
The disadvantage of course, is that we have to be mindful of how we
create op transactions, since each transaction creates an addressable
unit. For example, we must not include multiple patch revisions in the
same transaction.
The fetch implementation will potentially fetch the local operator's
remote, which is unnecessary and could result in deleted data.
Fix this by threading the local operator's public key and add an
ignore refspec to the fetch arguments, i.e.
^refs/namespaces/<local>/*
The implementation also strictly fetches all or one namespace. This is
improved upon by introducing a new variant for specifying a set of
namespaces.

The method `track_repo` only accepted the RID as the argument for
tracking.
Instead, allow passing Scope as an argument for tracking a
repository.

The tracking configuration has no way of consulting for a configured
scope.
This change allows the storing of this scope inside the tracking
`Config` -- currently unused.
The default Scope is chosen as Trusted, so that nodes do not
implicitly track any other node. If this behaviour is desired -- for
example, for seed nodes -- then All should be chosen.

The DelegatesOnly scope is very limited and causes more confusion than
it solves.
The Trusted scope subsumes DelegatesOnly since it implies delegates
along with any tracked nodes. This feels more natural to use and so
DelegatesOnly is removed -- leaving only Trusted and All.

Previously the alias field was simply a string which could possibly be
empty. Some checks were made to see if this string was empty.
Instead, make the logic more obvious by making the alias field
optional.

The MockStorage holds an inventory of repositories and their
identities but when asking for a MockRepository, none of this
information is transferred.
Add `id` and `doc` fields to MockRepository for defining some of its
functionality.
In addition, add a generator for a nonempty MockStorage to use in
tests that will expect the storage to be populated.

Getting delegates for a repository is a common task. A method is added
to ReadRepository for this, which default to fetching the identity
document, verifying it, and return the delegates for that identity.
The connect command was unimplemented for both Node and the control
socket.
This wires up the connect functionality in both places.

The routing function for Node was not implemented and there were no
functions for getting any tracking information.
This implements routing, tracked_repos, and tracked_nodes. To
accomplish this it was necessary to add associated types to the
Handler trait so that implementations could differ in the types they
use for returning this data, i.e. the control socket needs to use a
channel while the Node needs to return serializable data.
Currently, the Node uses a `Vec` but it would be more beneficial to
return an Iterator directly to ensure we are not always hitting the
heap.
To allow for the tracking types to be used across radicle-node (the
crate) and in radicle::node (the module), it was necessary to move
the types to the common place, i.e. radicle::node. At the same time,
new structs were added to make it easier to refer to tracked repos vs
tracked nodes.

Before this change, the identity document would be loaded for the
COB signer. This meant that a fork would be needed for that signer.
After this change, it's no longer necessary, since the identity doc
head is computed from available remotes.
While making those changes, it was also apparent that some of the
identity-related functions had bad names and error types, this
was fixed as well.
Previously, the seeds information would only consist of the connected
NodeIds.
Improve on this by adding any disconnected and fetching seeds as
well. A seed can either be disconnected, connected, or fetching --
where fetching implies connected.

It's fairly easy for a user to (by mistake or intentionally) create two
operations with the same OpId. This patch makes it much less likely,
and ensures that if the OpId is equal, it's because the operations
are identical.
Improvements to the CLI output as well as converging towards
`termion` as a backend.
The crates we were using for prompting and spinners were based on
a terminal backend called `console`, which is not really used
anywhere else. There were also limitations in terms of the output
of these crates.
Therefore, we switched to the `inquire` crate for prompting, using
the `termion` backend, which is very standard.
Additionally, we simplify the terminal output to use symbols:
! for Warning
✓ for Success
✗ for Error
... Instead of a mix of words and symbols.
We also include a modified version of the `yansi` crate which plays
well with our table formatting functions by automatically truncating
and padding output in a unicode-aware way.
The olpc-json crate's CanonicalFormatter does not escape certain
control characters, including new lines. This means that when a COB
gets serialized that includes new lines, those new lines are
serialized verbatim. Upon deserialization `serde_json` -- and any
other JSON deserializer -- will fail due to the encounter of these
control characters.
This behaviour was prevented in radicle-link with the definition of
its own CanoncialFormatter that encodes the control characters
correctly.
Inline this definition of the formatter, under MIT license, to ensure
the correct and remove oplc-cjson.
The behaviour is checked using a multiline test in the issue COB.
