Migration to Catkin build system

- deleted manifest.xml
- updated CMakeLists.txt
- created package.xml

This patch shuold be tested. It's also neeed to change the e-mail in package.xml, it was choosen a random e-mail to make the package compile with catkin


please consider to merge this patch, or to doing youreself the catkin migration: catkin packages can't depend on rosbuild packages, so all new projects based on Groovy can't use the driver anymore.
