Fixing spaces to tabs.

Grabbed the properties_game.py from my patched Trunk and attempted to get a better "merge" this time.

Also fixed up some errors from properties_scene.py from some stuff that was added after messing around in that file last time.

for svn merging sake's: rolling back last commit (fix for properties_game). I will commit the correct fix next

Using fully-qualified bpy.types.Panel instead of Panel. This was preventing
all panels from drawing.

Bringing the patch back into the branch.
The changelog:
* properties_scene.py now uses COMPAT_ENGINES properly
* fixed an error in space_logic.py
* changed cmake flag WITH_DDS to WITH_IMAGE_DDS
* fixed a crash with reading mipmap data in DDS files
* fixed an inconsistency in GPG_Application.cpp
* added a comment explaining why USER_DISABLE_VBO is set in GPG_ghost.cpp
* removed some code that was accidentally committed to refix a crash from libloaded lights
* fixed a memory leak with dynamic lights
* reapplied a fix for raycasting (seems to always disappear)

Thanks to Mitchell Stokes for the DDS fixes

Merge from trunk r40540

replacing cast from pointer from long to intptr_t (thanks Campbell)

pointers should be cast to long, not int (build fix for OSX+CMake+Make)

Merge from trunk r39703

Merge from trunk r39684

Merge from trunk r39354

VBOs now update when necessary.
VBOs are now interleaved to avoid iterating over the vertex list more than is necessary.
Removed some allocation/deallocation in the update code that was causing some slow downs.

Added color to the VBOs, this also happens to fix TexFace mode.

Recently VBOs started acting up when using display lists. Since the two really shouldn't be used together, and since using the two together cause no performance gain, display lists are disabled when VBO is chosen as the storage type. This is also reflected in the UI.

Sorted out some problems with scrambled UVs caused by the changes made for multiple UV support.

RayCasting makes use of collision masks. This needed to be updated to accommodate user settable collision groups and collision masks.

Fixed a crash caused by libload when no dynamic lights were allocated. Thanks to jplur for pointing it out to me on the IRC.

Looks like a merge from Trunk had messed up the change to have the bake menu in the game render panel. This brings it back.

Libloaded lights now work with the dynamic light settings.

The Desktop option is now greyed out when fullscreen is not checked rather than disappearing from the UI completely.
