* Got rid of the special-casing for the "mess" subtarget name.
* Got rid of the MESS-specific Windows resources, emuator info source
and man page.
* Added subtarget name to the internal name and original name in Windows
resources.
-ui: Put the system-specific items on the input settings menu together,
and fixed the crosshair visibility settings.
This will compile, link, and run a driver all the way to the first info screen, provided you use -video bgfx.
However, although there's a valid NSWindow created, it never actually appears on screen for unknown (but likely silly) reasons.
Inputs are not implemented and fullscreen exists but is untried.
