SnapdragonCamera: fix portrait orientation

Fix camera activity to portrait, so there is no delay when rotation
occurs. Main changes are:

  1. RotateLayout now supports padding and dynamically added child.
  2. Camera controls and gesture detetion are now orientation-aware.
  3. Toasts are replaced with RotateTextToast.
  4. Obselete layout files are removed.
