fteqw/engine/gl/gl_model.h
Spoike 567e9f112b added DP_QC_ENTITYSTRING builtins. 
mvd playback fixes/cleanups
r_fb_models more closely matches ezquake.
readded str[i] support.
fixed char constants (outside of strings).
string table compression no longer affects distinction between "" and string_null.
multiplayer savedgame fixes.
don't bugilly change hexen2's playerclass on loadgame, and preserve the STR_foo globals which are not marked for saving.
fix small bug on player renames. added a temp debug print to try to catch the issue onemanclan is having.
