Code review comment for lp:~laney/exaile/logind-shutdown

I apologize for reviewing this way after the merge was proposed.

I'm showing my ignorance here, but some questions come to mind about this:
- Is logind supported on all computers that ConsoleKit was found on? Or should we have something that uses both?
- Why shouldn't we use both interfaces, or do a detect of some kind to see if one or the other is there, and use the appropriate one?

Thanks!
