Vega Strike Code

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

The last commit message actually refers to src/gfx/cockpit.cpp. The changes to camera.cpp involved only triggering physics frame updates if actual physics changed, but passing the gfx update through regardless like it did prior. Also some dead variable removal.
