MythUI

As part of mythtv's on-going development effort, a new UI backend (called libmythui) is being developed and everything is slowly being rewritten to use this. This new backend allows multiple 'painters' that do the actual drawing - OpenGL and Qt based painters have been written. Using the OpenGL painter, a more modern/advanced UI is possible. At the same time, the process of rewriting converting Myth's UI to this new backend will allow everything to be made more consistant.
