Improved layout

Looks pretty good.
ApplicationItem class

Some new stuff:
	ApplicationItem class. A property of GestureItem, which probably will need to change name, as it isn't only the gesture, but also the application it's conencted to.
	Working selection of application, and viewing it through the whole app.
Sorted application list

And a few other things (OK, I forgot to commit).
Added a button on the start screen, which are to launch the actual launcher activity.
