The general idea is that we should have system themes that provide hints to
Wine about how to color itself in the form of a Wine-specific uxtheme file. 
Once we write these theme files for each system theme, Wine needs to learn to
probe for them in a standardized way at startup.  It could be as simple as just
throwing "winehints.theme" somewhere into the file, or it could be more
involved.
