* use QHash instead of Q3PtrDict
* use QList instead of Q3ValueList
* remove copied BubbleSort implementation of DiffModelList::sort(), instead use qSort with a custom comparison function which ensures the correct ordering (by value, not by pointer address)
* remove some unused Qt3Support #includes
* fix a leftover reference to K3Process in a comment
