Merge pull request #3 from shadow-robot/F_hand_cmdr_get_state_topic

Added a method to get the topic for the controller state callback.
Merge branch 'development' into F_better_sr_movements
added hztest for standard version of sr_movements, to check we're not breaking compatibility when upgrading to use the hand commander if a joint name is provided
created new Constructor to be used with HandCommander
instantiating the correct Constructor based on available parameters + added test for new joint name based sr_movement
making sure the joint name is upper case in hand commander received vector
no need to link if the package is in the dependencies in the manifest
reverted bad commit: those are made in the F_self_test branch
initial lower case
fancier parameter in test launch file
fancier parameter in test launch file
Merge pull request #6 from shadow-robot/F_better_sr_movements
