Install pr2.sh and pr2.yaml and add test codes

(CMakeLists.txt, catkin.cmake, pr2.sh, test)

Install pr2.sh and pr2.yaml.
Add test codes to use it.
In ``pr2.sh``, ``pr2.dae`` and ``pr2.l`` are generated ``/tmp`` directory, not ``euscollada`` directory.
This is because ``eucsollada`` directory will be ``/opt/ros`` directories and used should not write files in these directories.

This is derived from https://github.com/jsk-ros-pkg/jsk_model_tools/issues/49.
