Cosa è cambiato in EDuke32, build per build

Don't override the system allocator with nedmalloc and remove the unused nedmalloc code from polymer.c. This should fix a few crashes caused by ALSA and Mesa picking up memory allocator symbols from eduke32.

Memory cleanups, use Bm/c/realloc/free everywhere (configured as nedmalloc version in compat.h), add large page support for Vista/7, tweak nedmalloc settings, add support for projecting textures from SE50 spotlights placed in maps via sprite owner member (manipulated through CONs via sprite htpicnum member), fix building Mapster32 with MSVC, increase PR_MAXLIGHTS to 1024

stuff for fiddling with polymer lights
