Started using game-specific flags and removed/replaced some SCI version checks with flags.

Browse source 
- The SCI0 new script header and the angles check have been replaced by the GF_SCI0_OLD flag
- The SCI0 new drawpic parameter and the new priority check have been replaced by the GF_SCI0_OLDGFXFUNCS flag
- Removed the code which retries to use the newer script header in SCI0 games if the detected one is wrong, as that case should be covered by the GF_SCI0_OLD flag
- Removed the leftover min_version and max_version variables from gamestate
- Cleaned up kGetTime() a bit
