Why is rrbot.xml committed into the repo?

[dmiklic]

This file is autogenerated from rrbot.xacro, why is it in the repo then?

That is frequently done but is a bad habit that I'm trying to get myself and others to move away from. Are any of the launch files depending on the non-xacro version? If not, please open a pull request to move it, thanks!
