[NXThemes] style presets

OK, this is beginning to look like something 
there is now support for presets in the style editor, with a preview 
window that makes it easier to choose between the different values 
available. Presets are classified by categories (font, color, ..)

this is for the presets only, obviously there needs to be a more generic 
color picker, font chooser (as in photoshop), ... that is not limited to 
existing preset values.
