Subject: snap: UX improvements v1

 * Make the camera controls do sane things- get rid of the
   manual placement of every widget and use layouts
 * Animate everything correctly
 * Show ripples when clicking the shutter
 * Clean up a metric ton of dead code
 * Moved more code into BaseUI
 * Make setting up the camera controls less verbose and magical
 * Fixed up panorama layout
