Maxime Coste cfd7ee049a move selection updating code out of selection, to DynamicSelectionList
this avoids a lot of unnecessary (add|remove)_change_listener as
creating temporary Selections do not call that anymore.

Use can choose between a SelectionList which or a DynamicSelectionList
depending on wethear the buffer will be modified or not during the
selections lifetime.
