unfinished example of dummy gapplication by Hans Breuer

On Windows and Mac, gapplication based apps fail to start.

While waiting for native/better backend on the different OS, we could use a simple dummy backend as proposed by Hans Breuer.

A better suggestion may be to simply attempt to connect to the bus and, if that fails, proceed anyway -- as a non-unique application that makes no attempt to synchronise with other instances.

GApplication: don't fail if can't get session bus

If we can't get on the session bus, just behave like a normal non-unique
application.

This turns out to be remarkably easy to implement and lets us avoid
adding a 'dummy' backend.

Add a test for this case as well.

Idea from Zachary Dovel.
