Adds constructors (and #makeText) for Crouton which include Configuration object - there's one for Style already, and Configuration is just as basic a part of the Crouton. Adds a WARN default style to the Style class where ALERT is intended for informing the user about critical things which have happened, and WARN is intended for informing the user about critical things that are about to happen. Adds the dark equivalent holo color constants (as well as orange light and dark) from the Android colors.xml on API 17.
