Log Message:	revamp loggin. have a new log flag logBacktrace that logs the message and prepares a backtrace in the background, spewing it into the log at a later time. this is useful to shed some light on otherwise completely useless log messages such as: 2007-04-27 19:48:48.142 Calling random_roll with min=1 max=0 which could just as well not be there as we will never find out who is doing this to puny poor random_roll.
