Vega Strike Code

Another round of bsp removals, tweaks here and there dealing with the ray collider and collider system in general, and minor warning fixes.

Buffer overflow fix. We were writing beyond our array, bypassing usual merging from safemode branch to avoid the extra commit, however, it will be reflected in following push of un-related changes in that branch.

merging trunk -r12710 to safemode branch

Ticket #14 fixed - cube map texture addressing mode nondeterministically
set.

Minor optimizations:
- GFXOptimizeVertexList: optimized vertex compare function for faster
mesh loading
- AnimatedTexture: deferred setTime() bookkeeping for when the texture
actually gets activated, setTime() was figuring as taking up 6%
rendering time in profilings, whish is more than excessive.
- More debugging output. Yep, more is good, since it's off by default
(enable with --debug=3).

Raycollider is functioning, still some bugs to work out, beams (though i think this occurs in trunk already) dont stop when colliding with something. Also, some weird bug that causes certain ship textures to show up as all black. Very hackish right now. Much more to come.

merging trunk -r12706 to safemode branch

Warning squashing campaign complete. See accompaining ticket about unresolved tickets and needed peer review of changes made. Warnings as issued with current cmake setup, and gcc 4.4.1.

Merging with safemode branch -r12704, see log from that rev. Merge required for unitcollection and cmake fixes prior to non-mergable physics work

Ace reverted the collection list years ago and I just noticed now (going to remove old list code soon), removed unused physics code (more to follow in prep for physics work, but i'll keep any change in actualy run code to my branch), some other minor fixes here and there, major CMake tweaks, still need to see if our png detection needs to check for the new symbol that autoconf is now looking for
