Disable hover fade/opacity/transition

It really slows down the game (more than it already is–hello, Windows 95 stupid UI tricks) and makes dealing with the user interface frustrating and annoying. Note I am not referring to the “transitions” setting which does not seem to affect this hover fade/opacity/transition.
