added velocity values to marsIMU
fill calibrated_sensors putput port
added tiemstamp to _calibrated_sensors
fixed simulation time for release builds

data_broker connection code inside assert(), while asstertions are
removed by cmake and gcc in release builds "-DNDEBUG"
added min_range to MarsLaserRangeFinder

This parameter allows to set the minimal valid range
of the laser scanner
made Joint interface the same as all the drivers.
added transforms output to Joints task

This output is needed if the joint is registered
as a dynamic transformation provider
added an output port for the simulation time as /base/Time
fixed time output ports
fixed plugin connects (ability to (re)launch the simulation automatically by dependencies)
Joint: bugfix: In case of Position with velocity so not use setValue

setValue sets an instantanious speed. That is overwritten
directly by the mars intern PID controller. What we want is
to limit the maximum velocity using setMaximumVelocity.
Joint: bugfix read out the joint pos and speed not the last set values

The getValue and getVelocity calls on the motor return the last set
value, which is not what we want.
Joints: Accept actuator command that do not contain commands for all motors

The task was throwing before, as it expected commands for
the passive joints
register tasks at mars with their correct names
Revert "fixed plugin connects (ability to (re)launch the simulation automatically by dependencies)"

This reverts commit 70827f5d1f88381a0cdb1c62dc787ce46ddd6c78.

NO DON'T do this, a lot of plugins requiring the connection to mars
already in the configure hook. This patch will cause software breaks on
depending modules!.
added ability to rename mars joints in output ports
bugfix: make joints work again

Took status instead of cmd as input....
bugfix the bugfix: compiles again
allow to override positions from config files

may be used to have different configurations with a single mars scene
(move e.g. terrain position for different experiment setups)
updated doc for position override
