Fix head move during exit of example

Only moves head back to neutral at the end of the head wobbler
example if the clean_shutdown was triggered by finishing the ex.
This fixes the issue that the move could cause ex to hang if
program was actually interrupted.

Fix D-Pad button mappings on ps3 joystick

The ps3 joystick mappings in the joystick.py library were incorrect
for the D-Pad - specifically for D-Pad Left and Up did not work.
This fix switches them from thresholding the /joy message axes to
using the buttons array instead.

* Replace ps3 d-pad mappings with buttons instead of axes
  thresholding.

* ps3 joysticks have different axes scaling when connected via USB
  or BT - plus, Left and Up on D-Pad do not work in the former.

* buttons array works and is consistent in all cases.

Remove default from joystick arg in roslaunchs

Removes the default value for the joystick arg (joystick type)
in all roslaunch files for joystick examples. This matches the
examples themselves which require the --joystick arg to be
explicitly passed.

* Use ROS Remapping to pass joystick argument:
  $ roslaunch baxter_examples gripper_joystick.launch joystick:=ps3

* Accepted values are: {xbox, ps3, logitech}. (Also noted in
  launch file comments.
