Vega Strike Code

only include ftree parallel loops option if we want > 1 ... not sure if gcc checks for 1 to not include unecessary gomp in such a situation, so include it conditionally. Makes sense

optimizing collection class.

fix joystick bug

Significant GameUnit::Draw optimizations:
- LOD and cull mounts and halos separately (doesn't render them for distant objects)
- Do not abuse of WarpMatrix, memoize result

Merge previous particle improvements from trunk of which the last commit was dependant on

nevermind about isSun, but getRadius is still good to have since before only Unit could access Planet radius

Minor fixes to particle (reduce logging verbosity, fix out-of-sync comment)

Merge particle system fixes and optimizations from trunk

some minor cleanups and fixes

This is an attempt to reset fairness in scheduling in the game. Basically, since we're not threaded we have to decide how many physics updates we want to run per draw and this more closely tunes things to the settings the player makes with Computer (simulation_atom size). It's important when testing this commit to see if it should be reverted to make sure your settings are matched to your computer. Slow framerate will == jerkier behavior, but game speed should remain divorced from framerate for the most part
