Removed virtualreality (for use with vr helmet)

src/IDEAS

 * One binary, any game type. Store certain things in a new file?
+* A key to change viewsize at runtime (max == 20, min == 5 or so...)
+* Game able to cope at any virtual resolution in software mode. OpenGL
+  handles this transparently
+* Audio support using OpenAL

src/TODO

@@ -6,9 +6,13 @@ code, it really needs to be cleaned up
 * id_ca.c cache code: nice idea but messy and maybe can be fixed 
 in an effort to not allocate everything to memory and forget about it
 some sort of garbage collection
-* remove virtualreality
 * clean up header files, especially wl_def.h, where some externs arent in
 the right place
 * every structure that is read/written must be PACKED, with datatypes
 specifically set! (ie, no int, but short or long int)
 * is that memory intro screen needed anymore? probably not
+* fix the input code, everything is spread out... ideally everything should
+work the same, let the input handler do it all instead
+* when viewsize is around 20, sprites end up being drawn over the border.
+maybe there are clipping bugs that will cause it to fill over the top, left, 
+and right
\ No newline at end of file
