Enhance uxtheme to store the themed system metrics in the registry and 

also backup the old metrics. That way, themed system colors are set
even uxtheme was not loaded and initialized yet, and when a theme is
deactivated, the colors prior to the activation are restored as well.
Also, not having to set the system colors in uxtheme startup works
around weird problems where SetSystemColors() ended up being called
from inside window creation and this seemingly led to some creation
message being sent twice.
