[test] add ROS test

depth/video cameras and sick laserscan
sensor_msgs.msg PointCloud2, Image, LaserScan

You must patch ROS msg with:

    path -Np0 < patches/ros_python3.diff

see: https://github.com/ros/genpy/pull/9
[profile] add modifiers and datastreams profiling
[scenarii] ROS navigation tutorial exists using builder API
[depth] rewrite C module, "class" ZBufferTo3D

Allowing multi depth-camera in the same simulation. Former
globals are now wrapped in the Python ZBufferTo3D "class" (C
PyZBufferTo3D struct).
[profiler] do not record time if not profiling
[builder] add stereo mode and eye separation

see
http://www.blender.org/documentation/blender_python_api_2_65_release/bpy.types.SceneGameData.html#bpy.types.SceneGameData.stereo_eye_separation
Add support for service abortion with the socket interface

While here, improve logging msg when requesting an explicit abortion
[sockets] Fix processing of concomittent socket requests

Because we were using 'readline' only once on sockets ready to
be read, we could miss requests when several came in a row.

The Python 'readline' API is however blocking.

Rewritten this part to use low-level 'recv' and manually
splitting the buffer into independant requests.

This assume the whole requests arrive as a single TCP package.
waypoint actuator: improve behaviour when cancelling goto

It does not try to reach anyway the original target
[cmake] Integrate doc generation part to cmake
Happy new year Morse
[doc] testing fix ros commands
[builder] components classes w/ creator

WIP #221 - Will allow us to delete many binary .blend
files and save aprox. 8 MB
(we might keep them for backward compatibility)

Modify the test with those new classes,
move Human to morse.builder.robots.human,
set_blender_object w/matrix_parent_inverse.identity
  -> fixing GPS pose relative to ATRV (z=+0.10)
clean PassiveObject class
[builder] add cfg_radar Gripper
[sensor] fix kuka_posture init

was trying to get an instance from componentDict in init, while at this
moment of the simulation, the Kuka actuator might not be instantiated
yet.
[sick] fix bug when arc visible and no layers
[test] update ROS tests w/creator
[creator] update sensors meshes scale
[test] update robots w/creator and fix Z
[builder] update PassiveObject doc
