[wip/lwr-genom] Bump to 2.0

 Release 2.0
 - by default the lwr module is compiled without the kukaFri-libs
 - to use the kukaFri you need to set the kukaFri-libs option in robotpkg
 - lwr can control two kuka arms (named left and right) and one sahand connected to the right arm through the sahand poster.
