DebugDrawerComponent: implemented the new functions
	normalized doxygen comment style

now DebugDrawerComponent::Layer can be copied without problems.
the map now stores DebugDrawerComponent::Layer istead of shared_ptr<DebugDrawerComponent::Layer>.

added a setting for the debug layer name
fixed tooltips in graphics scene
elements now can be selected in the graphics scene with a double klick

fixed DebugDrawerComponent::drawCoordSystem (rescaling an existing pose did not work)

removed DebugDrawerComponent::enableVisu (use the ice function enableDebugLayerVisu)
added setScaledPoseVisu and setScaledPoseDebugLayerVisu to DebugDrawerInterface
added enableDebugLayerVisu to DebugDrawerInterface
renamed clear to clearLayer
