* 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
