Button styling is now much more "stylish". Additionally the way that the App.UserButton, related controller and handlebars template works has been cleaned up.
Basic home screen buttons launch popular photo screen. Back button triggers history.pop() on statechart.
Home screen displays 3 buttons, first button calls "showPhotoGrid" methond on homeViewDelegate controller that invokes "showPhotoGrid" action on state chart (too much indirection?), the state chart then calls gotoState("showingPhotoGrid") but that fails with: ERROR SC.Statechart<sc294>: Can not to goto state showingPhotoGrid. Not a recognized state in statechart
…point, I'm switching to a topic branch.
