Vega Strike Code

Bugfix: max_cubemap_size wasn't being taken into account by lightmap
loading code, only by (now deprecated) background code.

Reverted the cubemap edge fixup hack (set its default value to 0).
This hack is no longer necessary after fixing ticket #14

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.

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.

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.
