vk7js 206e827aeb Implement three levels of verbosity
Implemented the three levels of verbosity, besides none and beep:
1. Low: menus will speak but frequency and channel changes will just beep.
2. Medium: everything will speak but extra descriptions are eliminated except where ambiguity might occur.
3. High: Like medium except extra descriptions are spoken unles rapidly keying through menus in which case only the value will be spoken.
