Vega Strike Code

Updating branch to latest trunk. Try #2 - computer crash during first attempt

Updating binaries and VC9 files to latest svn

Issue #3325182: fighters being spawned as bases when dynamic_battle
chose a flightgroup for newly produced fighters. Had to exclude
the base flight group.

Trivial performance tweaks:
- range -> xrange (is a no-brainer)
- debug with lazy-applied format strings (ie: debug("doing %s",
something)), is quite fast when debug logging is disabled.

Make it easy to turn on python debug logging

Issue #3429854: Fixed derivative normals (were inverted, and didn't have
the normalmap ingame)

Print GL stats after each rendered frame with --debug=3
Useful for graphics performance profiling.

Make mesh_tool perform the same vertex de-duplication than the engine.
This enables off-line optimization and saves some effort from the
runtime, not to mention smaller files.

Do not draw super-tiny meshes (less than 2.5 pixels squared).
This was set at 0.5, but since it's computed based on the bounding disc,
and it usually is bigger than the mesh itself, 0.5 was overly
conservative. 2.5 gives better empirical results.

Trivial simplification: read once instead of four times
