specifically unlocked and so that you don't need to lock the non-SSID call in
order to lock an SSID call. So set/lock g1tlh will lock out all instances of
g1tlh, g1tlh-1, g1tlh-15 etc except (for instance) unset/lock g1tlh-9.
2. show/lock allows partial callsign matching so sh/lock gb7 will only show
GB7* calls that are locked.
3. Had a grand shift around for the start of NP.
fixed some of the problems with commands and no args
fixed sh.* = shutdown
fixed set/here doing both cluster and channel
added set/beep and made beeps only on user channels (not debug)
