c7f0dd737a Small changes in order to get the demos to work. Alien demo runs. Marine 
and Predator demos used a different HUD font.

Changes that need to be made for demo versions:
1. avp/langenum.h needs to be rebuilt for each demo (easy)
2. Marine and Predator demos need to use a different HUD font
3. There may be other minor differences with enums, etc.

drawn looks like garbage.)
