Kinetic migration

See merge request !1

# Conflicts:
#   launch/node.launch

 - fixed cfg update (gain_schedule was initialized with invalid -1)
 - reset_integrators: wait until values <0.01, with timeout of 10*100ms
iri_segway_rmp200_odom:
 - reset_odometry is now a service instead of a subscriber
 - yaw integration done in 2 steps (dt/2, dt/2)
 - tibi_dabo_odom.launch publishes on different topics/frames depending on mode. To launch multiple odometry nodes and compare.

 - added reset_integrators service server.
 - when segway->reset_integrators is called, check if integrators changed to 0.0

 - Changing wrong msgs dependency template <msg_package_name>_cpp to <msg_package_name>_generate_messages_cpp

Changed the name of the cfg file of the iri_segway_rmp200 node to avoid generating it every time.

   - ROS header added at the SegwayRMP200Status.msg
   - header fields filled at the segway_rmp200_driver_node.cpp (lines 57,58,59)

  - update launch files

 - Remove {tags/branches} from the top level of repository
 - Also setup.bash dissapear as rosinstall will generate its own. A new setup.sh
   was created inside scripts dir to handle automatically paths needed for them.
