Title: Added ability to specify an alternative renderer

My modifications and extensions to `CCoreTextRenderer` got a little unwieldy in a category. So I mimicked `+[UIView layerClass]` to allow `CCoreTextLabel` subclasses to specify a custom `CCoreTextRenderer` subclass.

I also exposed some private properties of `CCoreTextRenderer` in a category header to help subclasses do what they might need.
