Merge pull request #17 from BFALacerda/master

updated launch files
Changed the subscription for the teleop from /joy to /teleop_joystick/action_buttons.
Added a service to save the map.
Renamed the executable, namespace and launch file to represent that this is not only meant for joystick control anymore.
The waypoint recorder now subscribes to the /teleop_joystick/action_buttons topic instead of the /jot topic and offers services to call the saving methods.
Moved srv to ap_msgs and changed code according to new scitos_apps_msgs layout.
