catkinizes reem_common and adds launcher for visualising the robot model

[bit-pirate]

This adds a groovy-devel branch which contains the catkinized reem_common stack.
I have added a launcher (plus rviz config) for visualising the robot model using RViz.
The dependency on the pr2_mechanism_model has been commented out, since that stack hasn't been catkinized yet.

Hey Marcus,

Thanks for your work, this is the first catkinized REEM stack ever :-).

I can't merge the pull request into master as-is, because it would break our setup, which still relies on rosbuild. Still, I see two workarounds that would allow merging your work and make us both happy:

• I can create a groovy branch (groovy-devel does not conform to our current naming convention) and you can make a new pull request against that branch. This alternative requires the least amount of work.
• You could modify the pull request to allow the stack to be a rosbuild-catkin hybrid. We would then drop rosbuild support in a future time, when the official REEM ROS distro is one with proper catkin support.

What is your preference?

You are welcome! :-)

Well, I haven't done a hybrid package so far. Will PAL run parallel (rosbuild & catkin) for a while or is it more likely that you make a big jump to catkin with all ROS code in the near future. If the first is the case, it might be could considering a hybrid package. Otherwise, I would suggest to use a separate branch until PAL makes the jump.

We would make the jump to catkin once we start supporting a post-Fuerte ROS distribution, but this will not take place in the near future. Still, a separate branch seems the easiest solution.

Okay, let me know, when you have set up the groovy-devel branch and I will make a new pull request.

Created!

Just issued the new pull request.
