video: fix issue with throttling when mame runs at slow motion (-speed lower than 0.2)

ui: add speed slider when cheats are enabled

* 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.

resources.

and fixed the crosshair visibility settings.
