ID-Software/RAVEN-Software: original Dos-Heretic code

Andre Werthmann: Port of Heretic to Linux; works with BSD's too
		 (i have taken some code of chris's X11 and GGI doom-code)
		 
		 Rewrite of the Doom soundserver to work with Heretic,
		 that means Sfx-sound works now !



Jes Sorensen: has patched version 0.9.0, so Heretic works with Linux/m68k
		now !

Nic Bellamy: added SVGAlib code for 0.9.1.

Marcus Sundberg: Working GGI code. Keyboard fixes.

Lee Killough: fixes in p_spec.c
