Ykkrosh ee3243ff92 # Fixes for simulation speed in scenario edtior. Various code cleanups.
Game, Simulation, etc: Separated 'update' and 'interpolate', and made
'update' return whether it's going fast enough (so callers can decide to
do more updates per render). Changed some time variables to 'double' so
they have enough precision in long games.
Atlas: Added "Fast" playback button. Made simulation sometimes go at
real-time speed, if it's just slightly too slow at rendering.
VertexBuffer: Removed some non-useful glGetError calls.
Entity: Commented out redundant Tick code. Fixed syntax error in
disabled code that confused the IDE.
Aura: Changed string code again, to simply use ASCII instead of UTF-16.
(SpiderMonkey seems to handle it just as efficiently, for small
strings.)
Misc: Some more minor header-file cleanup.
SVN log: Added feed link.

This was SVN commit r4807.
