Xash3D experimental fork

[bart]

New build:

• Added func_eye in hl.dll, brush entity that looks at the nearest player, toggled by using it in any way, give it an origin brush!
• Added function: CBaseEntity *UTIL_GetClosestPlayer( CBaseEntity *pEnt ) - gives the nearest player, dead or alive

This is only experimental entity to see how adding custom ents works and rotation of brush-based entities.

Here is a map that shows functionality of func_eye (try ent_fire eye1, eye2, eyemm)
