commit dfd5dd47d4008fd0cffce35957db0ce0116da4cf
Author: Emmanuele Bassi <ebassi linux intel com>

Add GApplication
GApplication is a base class that encapsulates an application.
Every GApplication is, on systems with D-Bus available, exposed as an
object with a well-known name on the session bus; a GApplication also
exposes "actions" as D-Bus methods through introspection.
By default, a GApplication is a single instance: no more than one
GApplication with the same name can exist at the same time.
