shrunk entity_t struct a bit (by removing some stuff from persistent which had similar/identical values in render)
restructured/refactored some of entity relinking (now all relinking happens in cl_main.c where it belongs, moved viewmodel stuff out of view code)
restructured how viewmodels are handled
streamlined/cleanedup/refactored V_CalcRefdef (and merged in V_UpdateBlends and V_AddIdle and V_CalcBob)
