test classname `properly' (ie, with -classname) bot_move.qc: re-implement the lost obstruction detection code in a way suitable for the new physics handling. Probably needs tuning. bot_qw.qc libfrikbot.h: Break and itos for debugging waypoint.r: implement -realorigin. oops. that caused how long a wild goose chase?
