A couple more simple gcc4.X warnings fixed.

softbody.c I removed an unused var.
text.c added return values to 2 return statements that didn't have anything.
Makefile added $(FIX_STUBS_WARNINGS) to CFLAGS for the stub.
source/blender/src/editface.c  fixed up int vs unsigned int stuff
source/blender/src/resources.c had two vars declared as unsigned char *
and then inputs to them were cast as char * so updated the casts.
