Checkpoint commit with many different changes. Made the Configuration and Simulation "add" buttons to be action bar items. Added Handler to act as a listener mechansims so the OpenRocketViewer can update fragments when the rocket is modified. Added MotorConfigSpinner as custom View which is more usable than MotorConfigSpinnerAdapter.
