fixed back button

-moved #menuButton onclick function into home.controller.js
-set snap options (disable/enable) based on state.
oh dude, forgot to tell you, you don't have to do that here.  You can do that using "resolve" from ui-router: https://github.com/angular-ui/ui-router/wiki#resolve

what this means is that when you get into the prayer and prayerAdd page, the resolve function will execute first.  You can use that to disable it and set the right things before entering into the controller.  Or you can use the "onEnter" callback:  https://github.com/angular-ui/ui-router/wiki#onenter-and-onexit-callbacks
