small demo program

As can be seen in the demo program, the first time an item is selected from a treeview two "changed" signals are emitted. The first one pointing to the first item in the treeview, the second one pointing to the item actually selected. This can only be observed if the first selected item is not the first item in the list.

    treeview: Move all button press/release management to the multipress gesture

    The multipress gesture on the bin window now also does all the business related
    to row selection. As row selection and activation can't be easily decoupled, this
    fixes certain problems around ::row-activated being emitted on NULL paths.
