- replace a few constant values with GL macros in tr_cmds.c

Browse source 
- tidy up top of tr_types.h a bit, change flags to hex representation
- make ROM cvar enforcing really work
- remove cg_stereoSeparation from cgame as it is obsolete.
- Add CG_DrawCrosshair3D so people see crosshair correctly when stereoseparation is enabled
