[Merge] lp:~gerboland/qtubuntu/enable-debug-mode into lp:qtubuntu

[Gerry Boland]

Note: this requires work on unity8's side before it is functional. But it works with mir-demo-server.

Also note, mir only supports this mir-client-debug extension if the mir server is started with the --debug argument.

This will be a problem for application autopilot testing, as it will require unity8 to be restarted with the --debug flag now.
