Added terminal chooser combobox
desklets: trigger on button-release.  Desklets are draggable objects like
panel launchers and window-list entries, so they need to keep to the old
behavior so as not to complicate distringuishing between drags and clicks.

Fixes #3363
Convert panel launcher applet to settings API, introduce 'panellauncher' applet role,
to allow "Add to panel" in the menu applet to target third-party applets.

To prevent a loss of usability, the default panel applet will still be added to the
panel, if the role has not already been claimed.
