shellDBus: Add UngrabAccelerators

Browse Source 
While it is possible to register accelerators in-bulk, there is no
proper way to unregister them again. This adds the corresponding call
for UngrabAccelerator to allow ungrabbing multiple accelerators at the
same time.

The idea is that g-s-d can use this in the future to simplify the
keybinding reload logic.
