NPCServer & GServer updates

[Admins]

(May be there should be a special forum for these kind of messages?)

Several things have been updated, you need to restart your server to make them work:
- updateboard/updateboard2 work correctly on gmap now, sending the correct tiles to the gserver and players
- mass pms of players on staff tag are sent to everyone and are not blocked, even if the staff has adminlevel 0
- the playerlist status icon is sent to RCs at login (important for RC2)
- speed optimizations for the gserver when sending already compressed files (pngs, mp3s etc.)
