GUI now supports basic interactible widgets, widget colour and border are more unified, and some code cleanup. Removed some circular dependencies which slipped in. As a result, the OpenGL code got separated into different files. Enabled widgets to recieve events. New IParentWidget interface allowing widgets to interact with their parents. New Widget base class. New WidgetDecoration class. New ButtonWidget class responding to events (in a basic way). committer: Diggory Hardy <diggory.hardy@gmail.com>
