clean-up and some new recipes

These commits cleans up a previous attempt for ROS fuerte that is now discontinued.
Also due to our work on cross-compilation on catkin and some experiments, the recipes for the native compilation degraded. These commits revert the files we are not currently working on to a state where I believe that native compilation works, but I have not checked that. 
The commits also add some new recipes. I believe that now all recipes for the package group ros-comm should be there, but I have not checked that. Not all recipes are functional yet.
