Run recording is pretty much finalized.

Runs are now renamed to have your final time in it.
Time is accurately calculated now.
Cleaned up a bunch of stuff.

TODO:
* ent_fire trigger_knockout_teleport enable = start of portal
* Make a converter to strip the ghost type byte from old runs
* Splits - generated from run files (use the run analysis method to make
them)
* rear view mirror and speedometer
* networking and portal port
