Subject: [PATCH] Implement a CLI tool allowing to add remote plasmoids

Use the D-Bus call on the Plasma Desktop shell to create a cli helper
tool allowing you to add a remote widgets based on its URL. So something
like "plasma-remote-helper plasma://host:port/name" will add the
plasmoid "name" exported from "host" to your current activity.
