Title: Label background color

Problem: You couldn't assign a backgroundColor directly to a label. It is initialized to clear.

This can lead to performance penalty, as described in this post: http://blogs.captechconsulting.com/blog/john-szumski/performance-tuning-older-ios-devices

Solution: Enabled setBackgroundColor_ for label. Performs as before - if no color given, defaults to clear (transparent) else assigns bg color to the label directly. If dev's care, they can take the time to set the proper label backgroundColor now.
