Changed goal in altitude_node to be current height when enabled.
Added PID subscribers to altitude_node
This should make testing at least a little easier, until we come up witha better way. Also, moved joystick_control.launch to where it could beseen globally by ROS.
Minor changes in preparation for test flight.
-Added parameter default_goal to altitude_node-Changed joystick button for toggling altitude control to button 11 instead of 1.
Nevermind... didn't need those
Adding some files to arduino so it compiles
These files are generated by rosserial, but they don't need to beregenerated by everyone, and I don't remember now how to generate themanyway.
Moved mikrokopter to quad2
