[CMake] fix for CMake 3.5

VERSION_GREATER_EQUAL is not available. Switch to NOT VERSION_LESS

They have been moved to roscontrol_sot_talos
in repository talos_metapkg_ros_control_sot

Release v1.2.1

To keep retrocompatibility for sot-talos-balance,
but we have to find a relocatable way to do this.

[scripts] Add python file to start simulation for 16.04

See merge request pyrene-dev/talos_data!12

Explain the goal of this script -> it is a temporary fix which hardcode the talo_data path

Warning: It doesn't start the roscontroller, you have to launch it in another terminal with "roslaunch roscontrol_sot_talos sot_talos_controller_gazebo.launch".
Otherwise the data are not correctly dumped when the process is killed.

Moreover it removes the call to moveit and several serves useless for
the SoT.

For now the arguments are not working on bionic.
It is not specific to python but rather seems to be related
to a new usage of roslaunch.
