refactor WM_COMMAND messages handling in MDI frames to avoid duplicating code unnecessarily and generally streamline it; added possibility to use custom menu commands in the "Window" menu and specifying accelerators for them now works too (show this in the sample); finally added standard ids for the MDI window menu commands
