Clear the data when the model resets.

This patch does a few things:
1 - reset the model when user closes the dive file
2 - connects the 'rowsAboutToBeRemoved' in a way that the graphics can
    remove their polygons too
3 - adds a 'clear' virtual method so items that don't follow the rules can
    clean themseves up.
