[doc] Minor change in generate_doc
[teleport] Added 'translate' and 'rotate' services
Large rewrite of armatures management

Should close #86, #231 and #232

The commit now clearly separate the 'armature_actuator' and the
'armature_pose' sensor.

You can find their respective documentation here:
- http://www.openrobots.org/morse/doc/latest/user/actuators/armature_actuator.html
- http://www.openrobots.org/morse/doc/latest/user/sensors/armature_pose.html

Now supports:
- armature with a mix of prismatic and revolute joints
- taking into account speed when moving (ie, no more instant 'jump'
 to target position)
- default actions are implemented for both the armature actuator and the
  armature sensor to write/read armatures pose.

Two new/update unit-tests cover these features:
- armature_actuator_testing
- armature_pose_testing

This commit also remove the kuka_lwr and kuka_posture components that
are now obsolete (note: KUKA documentation still need to be updated).

This commit also include a documentation on how to create Blender
armatures that work well with MORSE.
[armatures] Armature sensor must now be parented to its armature

Previously, armature sensors would get a reference to the armature
the monitor throught the 'armature' property.

Now, armature sensor just need to be parented to their armature.

This ensure it will work with the 'auto-renaming' patch.

While here:
- improved error message when armature is not found
- renamed ArmatureActuatorClass into Armature
- fixed gripper_testing
- removed kuka_lwr_testing
[actuator] Fix the name of variable exposed in local_data

Must be v, not x :). It works with socket unit-test because we blindly
rewrite local_data in socket datastream stuff, but it is not the case in
some other middleware (yarp for example)
Missing name change after renaming of armature_actuator to armature

While here, remove kuka_lwr from cmake as it has been removed
Invert the PTU/PTU sensor parenting order

This is to be consistent with armature actuator/armature sensor.

While here, updated doc for auto-generation.
[doc] Minor doc update in armature_pose
[testing] Add missing armature_pose to cmake
