2.5

Summary of ain features:
- Themes and Styles are now editable.
- CTRL+U "Save user defaults" now goes to new .B25.blend, so you
  can use 2.4x and 2.5x next to each other. If B25 doesn't exist, it
  reads the regular .B.blend
- Press Tkey in 3d window for (unfinished) toolbar WIP. It now only
  shows the last operator, if appropriate.
  Nkey properties moved to the other side.

A lot of work was done on removing old themes for good and properly
getting it work with the 2.5 region system. Here's some notes;

- Buttons now all have a complete set of colors, based on button classifications
  (See outliner -> user prefs -> Interface
- Theme colors have been extended with basic colors for region types. 
  Currently colors are defined for Window, Header, List/Channels and
  for Button/Tool views. 
  The screen manager handles this btw, so a TH_BACK will always pick the
  right backdrop color.
- Menu backdrops are in in Button theme colors. Floating Panels will be in
  the per-space type Themes.
- Styles were added in RNA too, but only for the font settings now.
  Only Panel font, widget font and widget-label work now. The 'group label'
  will be for templates mostly.
  Style settings will be expanded with spacing defaults, label conventions, 
  etc.
- Label text colors are stored in per-space Theme too, to make sure they fit.
  Same goes for Panel title color.

Note that 'shadow' for fonts can conflict with text colors; shadow color is
currently stored in Style... shadow code needs a bit of work still.
