Overhaul of parts of the polyblend system. Contrast in GL no longer uses

Browse source 
another alpha blend, it's set up exactly as another factor in determining
the final blend. This should help speed up framerates a little.

New cvars:
cl_cshift_bonus: Set to 0 to disable bonus flashes.
cl_cshift_contents: Set to 0 to disable content blends.
cl_cshift_damage: Set to 0 to disable damage blends.
cl_cshift_powerup: Set to 0 to disable powerup (quad, pent, etc) blends.

All of these cvars work for both GL and software, and all of them check
the value of the "cshifts" serverinfo. cshifts is a bit field, with the
following bits defined:

bonus: 1
contents: 2
damage: 4
powerup: 8

An admin can force any of these to be respected by choosing the numbers of
the cshifts to be enforced, and adding them up.

examples:

serverinfo cshifts 15

turns them all on.

serverinfo cshifts 10

turns on powerup and contents shifts.

also, the gl_cshiftpercent Cvar no longer does anything. I'll remove it
entirely soon.
