switch shader variation from runtime-with-tags to dynamic with #ifdefs;

Browse Source 
support making all definitions static so you can have multiple copies of file (with different #ifdefs);
move all tables to end of file (this will have to be undone later because IIRC it's not compatible with C++ or with some compilers or something, but it'll make my life easier in the interim);
