This fixes BGE bugs #30484 (Frame rate increases very high after game engine start with record animation enabled) and #29449 (Record Animation runs 1000+ fps on Mac OSX 10.6.8 64bit). The problem was, recording animation was forcing "fixed time", which always advances the engine one frame instead of advancing based on time passed. This means that "fixed time" runs at full speed. Now fixed time is disabled when recording animation.
