frontlib improvements: - Added README with overview documentation - Improved code documentation/comments - Added flib_gameconn_send_quit to gracefully exit a running game - Changed the type of some size variables to size_t - Fixed starting a mission/training sending the mission script like a multiplayer script - Removed reference counters from flib_scheme and flib_map - Removed INGAME state from netconn (there is no useful difference to ROOM state) - Added extras/jnacontrol.c to warn when functions signatures used by Hedgeroid change - Other small code improvements
Ignore whitespace changes - Everywhere: Within whitespace: At end of lines:
