Alles neu macht der Mai... Äh Juli. Wie auch immer.

Build 376:
- show network drives in /drives command (by JacK)
- option to disable Flashing for Spieleplanet bot (by JacK)
- report "nickname in use" message to active window, not Status
- report "erroneous nickname". (wtf? why was this message not shown before?)
- added option to invert rotation-key for tetris
- removed pong
- rewrite of netpaint protocol (7 bit now to be encoding-independent)
- whois on doubleclick in channel window
- user picture new date as picture-id to not save the same picture again and again
- hopefully fixed avatar appearance for old VB6 servers
- make randomization of space position for tetris random again (without breaking compatibility yay)
