Second checkpoint commit of OpenRocketLoader to make it orientation change safe. Changed Main.java to register onclick listeners in java instead of the layout. Store the WarningSet in Application so it doesn't need to be serialized if the OpenRocketLoaderActivity is recreated during an orientation change. Fix the MissingMotorDialogFragment to only have the string and not the whole WarningSet. Finally completely rewrote the OpenRocketLoaderTask into a Fragment managing its own dialog.
