The value of `RAD_SOCKET` influences the outcome of `cargo test`.
Users that set this environment variable to, e.g. point `rad` at
a socket at a custom location, were surprised that execution of
tests would interact with their node.
Split `Home::socket` into two functions. `Home::socket_default` is
"pure" and only dependent on the path represented by `Home`. On the
other hand, `Home::socket_from_env` interprets the environment.
Most users will want to use `Home::socket_from_env`.
The `help` module is no longer needed, since `clap` handles that.
This meant that the re-exports of each command's `ABOUT` could be removed and
the `const`s can now be private.
Rewrite module declarations that use the `#[path="…"]` annotation
to the more idomatic `pub mod …` + `pub use …` forms.
For the "self" module, that is not possible because `self` is an
identifier in Rust, and also `r#self` is not admissable as a raw
identifier, so stick to `rad_self`.
Files in submodules were patched as appropriate.
Pay more attention to when a Node ID is displayed in compact form. As
this was sometimes used to save space, e.g. in `rad node status` in
combination with long node addresses (like .onion names), also implement
a compact format for node addresses and use that instead in some cases.
Progress notifications in spinners keep the short form.
