Vega Strike Code

A more proper fix to the python3 version suffix issue: tell CMake which suffixes to check.
Works in openSuse 12.2 (CMake 2.8.8). Sorry if it breaks it for you safemode, feel free to revert in that case.

Python 3.0 and 3.1 compatibility: PyEval_EvalCode received PyCodeObject
in those versions.

GCC 4.5 compatibility fix: only use warning pragmas in gcc 4.7+

to appease the masses

minor optimizations to sdds ...not that anyone with a video card that would use sdds could run the game

Some minor hopeful fixes to some collision related code that hopefully helps make collisions with objects less buggy. Also attempted to fix what looked like a bug in the polygon code reading in quad polygons (which we don't do anyway) where the triangle reading code executed after numtri's was reached in the second iteration of the outermost loop.

small tweaks to get some better autovectorization

Sorry, killed the s in unsafe-loop-optimizations

Minor cleanup in options class and apparently we were overriding cpu opts with a standard -O2 release flag, this disabled the -O option set in cpu_opts (disabled vectorization which is turned on by -O3 by default in current gen gcc)

Another set of options consolidation. Only about a thousand more left.
