Merge pull request #3398 from RavetcoFX/a47

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.
panel-launcher applet: Obsolete old gsettings key, auto-populate the new launcher settings
with the old values (once), expose setting for inhibiting individual launcher dragging.
xlets: allow multiple instances of a role provider.  Make panel-launchers
a multi-instance applet.
panel launchers: Allow dragging between launcher applet instances
panel-launchers: show immediate visual feedback when finishing a drag/drop
operation.
Add DND launcher prototype to facilitate drag and drop of launchers
between different launcher applets.
Merge branch 'launchers'
Make launcher editor able to work with/update xlet settings, fix panel
launcher applet to use it.
