Crawlas now use only one state for looking each SPR2_ constants added to dehacked.c for use in SOC/Lua (both "SPR2_RUN" and "SPR2_RUN_" are in theory the same thing in this implementation, likewise for other 3-char name cases) spr2names array/table also added for use in Lua - it works identically to Lua's sprnames, only with SPR2_ constants/string names instead Some minor cleanup for OpenGL sprite/MD2 code
