Title: Add optional background for scroll-above area

The background color can be customized with the refresh control's `backgroundColor` property. By default, it is a light blue color which works well with native UIKit components. The background can be disabled using the refresh control's `showsBackground` property.

I've tested this to ensure it works and rotates/resizes well on iPhone, iPhone 3.5" Retina, iPhone 4" Retina, iPad, and iPad Retina screens.

I've tried to maintain iOS 4/old-Xcode compatibility in this code, but I might have missed something. Additional comments on cleaning up my code are welcomed.
