Adds fixed frame frequency.

Browse Source 
Adds possibility to control the frame time by setting the frame
frequency by a command line argument (`-fixed-frame-frequency`). It's
mostly useful for a trailer recording and graphics debugging.

-hashtest-quick=X whether to enable computation of quick hashes in replaymode (default false). Can be enabled for debugging purposes.
-fixed-frame-frequency=F fixes the frame time. With that flags it equals to 1/F. For example,
if F=60 it means the game behaves like it's always running with 60 FPS.
