ListBox should inherit from DeathListener and remove select listeners upon death events #69

On a second thought, selection listeners are not widgets. This is an unsolvable 
problem. If a selection listener is deleted and not removed from a ListBox, 
Guichan 
will crash if an event is fired. Perhaps it's acceptable.

This is one of the reasons why Qt has an object (QObject) on top of QWidget, 
which
has death-listener like functionality. Anyway, I think it is perfectly 
acceptable.
I've added notes in the documentation about this for ListBox and DropDown in 
revision
1120.
