Lots more work on the GUI. Also renamed lots of files. Lots of changes to the GUI. Renderer is now used exclusively for rendering and WidgetDecoration is gone. Renamed lots of files to conform to case policies. committer: Diggory Hardy <diggory.hardy@gmail.com>

21 * wrapped in another function before being run in a thread (i.e. run indirectly). Functions fail
22 * either by throwing an exception or by returning a boolean. Functions may take parameters, e.g.
23 * "out cleanupFunc[]". */
