added prototype ListWidget (doesn't do anything yet, only serves to demo how it might look); renamed various NewGui methods and added frameRect method; made NewGui use our 'own' GUI colors (no worries if you don't like them, this is just an experiment); StaticTextWidget now clones its label (preventing problems when a game was loaded, thus invalidating string locations in memory)

+ * Some thoughts:
+ * - We should split out the scrollbar into a seperate widget. This will
+ *   simplify the drawing & mouse handling considerably, but also requires
+ *   us to come up with a way to couple both widgets (shouldn't be to hard)
+ * - Write a class to encapsulate the data instead of using std::list<string>.
+ *   How exactly this will look and what it does has yet to be determined.
+ * - The handleKey method of widgets is currently never called, code for that has
+ *   to be added to dialog.cpp
