pr_comp.h:

add OP_ADD_S. WARNING!!! this /will/ move.
progs.h:
	add prototype for PR_PrintStatement
pr_edict.c:
	add OP_ADD_S support in the progs checker
pr_exec.c:
	implement OP_ADD_S
tools/qfcc/include/.gitignore:
	add config.h.in
qfcc.h:
	nuke PR_NameImmediate and change PR_ParseImmediate's prototype (see
	pr_imm.c)
pr_comp.c:
	add ADD_S, adjust for PR_ParseImmediate's prototype, make
	PR_ParseExpression work with non-sequential opcodes (slow, will work on
	that next). Fix up initialised global parsing.
pr_imm.c:
	nuke PR_NameImmediate. didn't work well and wasn't such a good idea anyway.
	PR_ParseImmediate now accepts a def_t * arg. if null, will allocate a
	new global def, otherwise it will initialize the def passed in.
qwaq/main.c:
	sports some debugging code (dumps info about the progs it's running)
qwaq/main.qc:
	better ADD_S testing
