Use appropriate subclassing in CPColorWellValueBinder
Added valueForBinding:
Formatting, import fixes
CPProgressIndicator fixes

- Make height 20px, same as in Xcode, so we can actually lay them out correctly without guessing. And they were just too tall at 25px anyway.

- In case the height does change in the future, calculate the correct height from the theme in NSProgressIndicator.

- Updated the theme descriptor to include the default height.

- Updated Aristo 2 PSD progress indicator artwork.

- Moved init of CPProgressIndicatorSpinningStyleColors out of layoutSubviews, it is file global and only needs to get done once.
Fixed missing ivar and updated url
Eliminated the "SomethingElse" framework that no one actually removes, declared theWindow as an @outlet to make XcodeCapp happy.
Added a totally gnarly example of how to do complex custom data views using Xcode and bindings
