Make AutoSegmentationTool label aware
Add non const option for mitk::AutoSegmentationTool::GetImageByTimeStep
Added label awareness to AutoSegmentationWithPreviewTool
This implicitly fixes the threshold tools (T29096 and T29097)
Makes picking tool label aware and improves it.
Fixes problems with overwritting other labels.
Now you can also pick from multiple other labels and the picked
elements will be added to the active labels.
Be aware if you pick from other labels the must not be locked,
other wise the lock will be ignored.
If you pick from the active label it is irrelevant if it is locked.

Fixed gcc compile errors
