FPS issue fix

[EnforcerRidley]

So, it's recommended by numerous sources to cap the FPS at 30, but I found at 30 FPS that I was still slipping and sliding to my death on Gall Spaceport. This didn't happen on N64. So what was the FPS on N64? About 25 FPS.

Based on the fact that Shadows of the Empire on N64 was 25 FPS, I capped the FPS at 25, and the slipping and sliding on Gall Spaceport completely stopped. It may not look smooth anymore, but, at least, the game runs better without the gravity issues.

So, cap Shadows of the Empire to 25 FPS instead of 30 FPS.
