Merge pull request #26 from nilsbore/master

Add chest_xtion camera in urdf file, add calibration of chest camera with respect to ground floor. Ok, I'm merging this now. I think this repo is a good place for the calibration nodes since the precision of the urdf tree is highly dependent on the calibration being run. We've been running this for a week and everything seems to work. Also, it shouldn't matter for the ones not having a chest camera since they would only get a few extra links in the urdf.
