[edit] List of Bugfixes

Codechange: Allow standard ini-file style comments (Wink (r6972)
Codechange: Send server messages with format NETWORK_ACTION_SERVER_MESSAGE so it is general colour like the rest of the server messages. Spectators speak in grey (r6932)
Codechange: Change textmessage format a bit. Only the sender's name and target are in the sender's colour, the actual message is in white. Should improve readability (r6932)
Codechange: Add an MD5 sum check of our own data files, and warn if they don't match (r6921)
Codechange: Add strict bounds checking in string formatting system to check for possible buffer overflows (r6884)

Fix: Go to hangar orders for aircraft could get spuriously removed when a road or rail depot got deleted (r6355)

Fix: Never allow scrolling the map in the main menu (scroll-settings weren't reset if switched to mainmenu) (r6037)
Fix: Never set I-am-a-thread bool to true IN the thread, dual-core machines could flip [FS*78] (r5977)
