Changed namespace to teleop_joystick
Created a message for the action buttons
Merge pull request #2 from cdondrup/master

Moved rumblepad_control into scitos_apps/scitos_teleop
Now publishing a custom button message containing 4 bools, one for every action button.
rumblepad_control is now checking if the pad runs in teh correct mode to prevent confusion because of a wrong button layout.
