dependencies (scfglib*.c, scfglib*.c, etc.) for the single-threaded SBBS
that need to load the configuration (*.cnf) files from ctrl.
Rather than updating 8 projects every time the load_cfg.c dependencies change
and rebuilding 8 times, just use a lib.
Also fixed-up some linker warnings about EDITANDCONTINUE, blah, blah, blah.
