Vega Strike Code

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.

More consolidation of options into vs_options class. other minor cleanups

First round of option consolidation. many many more to come

Some double -> float issues cleaned up

missed this little warning

More warning fixes, this is pretty much everything other than double->float narrowing issues. which are fairly complicated compared to these guys
