Code review comment for lp:~mblayman/entertainer/start-fullscreen

This branch fixes problems that Entertainer has with fullscreen. It changes the default configuration so that Entertainer starts in fullscreen by default. This should work on all screens so it should eliminate the whole class of questions that say "how do I get Entertainer to fit on my <small resolution screen size here> screen?"

It also adds the GTK window back back and I fixed up a number of issues related to the window mode. The close button now works and I've added the Entertainer icon to the window.

The toggle between fullscreen and window mode still isn't very good, but frankly, neither is what we had. The root of the problem there is that we don't currently have a way to repaint the currently displayed screen. Adding that capability would make this branch enormous so I haven't done it (and I think Samuel had put some effort into that).
