use condition attributes to specify Python 2 and 3 dependencies #71

I am following the same convention how catkin chooses the dependencies based on Python version, so different rosdep keys can be selected depending on the build environment.

Thanks for the patch. I just merged #75 since I forgot about this PR. This patch needed to change the format version in order to allow the condition attribute to be used.
