1. fix set/lockout so that it is possible to lock out all SSIDs except those

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.
