Comment 15 for bug 930488

I started working on this too, then found the patch in this bug so switched my work over to incorporating this patch in a bzr branch. It's at lp:~laney/lightdm/logind but I'm happy to have it in any shared location. I'll try to work on the tests too.

I add some defines and a configure flag to enable/disable consolekit/logind. It's not strictly necessary though and could be removed if people would prefer to just do runtime detection.
