Initial import of the Text actor from Tidy
The TidyText actor is meant as a replacement for both ClutterLabel and ClutterText. Any text-displaying and editing actor should derive from ClutterText and implement the various visual cues to differentiate the editable from the non-editable state. Those visual cues usually belong to a high-level toolkit, especially if themeing is involved.
