Sync to signal ops; removed links-and-tags tests; removed dead listeners from links module; removed FramesLeft global in player module; removed unused  from string module, now stock Lua again; massive redesign: all use of dispatch lists now use Runtime event dispatches (sometimes indirectly through AddMultipleListeners... a not-too-far-away update may in turn ditch those as well, in addition to removing the dispatch list module)... massive testing to follow, I suppose
