2.5

Transform:
First working port of the transform code:
- Object mode only (other conversions need to be ported)
- Contraints (global and local only) working
- Snap (no edit mode, obviously) working
- Numinput working
- Gears (Ctrl and Shift) working
- Only grap, rotate, scale, shear, warp and to sphere have been added as hotkey, but the rest should work too once accessible
- No manipulator
- No drawn feedback other than moving stuff and header print (no constraint line, snap circle, ...)
- No NDOF support

I've only tested Scons support, though Makefil *should* work, I *think*.

Misc:
-QuatIsNull function in arith
-Exporting project_* and view[line|ray] functions from view3d
