doc builds are failing

[gavanderhoorn]

At least for the hydro-devel branch (but I don't think things have changed sufficiently to have improved in the newer ones). From here:

03:24:17 error: package directory 'motoman_robot_pkg_gen' does not exist

Could be that #17 and #18 have fixed this.

kinetic-devel branch now has a successful doc build, and with #25 Indigo should be ok as well. CLosing for now. Will re-open if necessary.
