Merge lp:~vikoadi/audience/fix-1040729 into lp:~audience-members/audience/trunk

[Viko Adi Rahmawan]

1. Create Utils.GnomeSessionManager
2. create VideoPlayer.set_screenlock method and call it from VideoPlayer.playing setter

[Cody Garver (codygarver)]

I have been testing this and it works as advertised.

Just waiting on Tom Beckmann to get some time to check it out before merge.
