STYLE: updated documentation on selection node

Updated doxygen comments to note that the PlaceNodeClassName
calls replace the AnnotationNodeID calls. 
Fixed a merge error on the enum, fixing the overwriting of event
numbers and moved the UnitModifiedEvent to be last.
Updated doxygen comments on the annotation fiducial node to
note it as deprecated moving the top level description so that
it shows up on the generated pages.

BUG: update the CLIs to create new Markup fiduicals from point node selector

The command line module GUI helper hadn't been updated to create Markups
Fiducial nodes by default when creating new nodes was enabled. It was still
set up to create Slicer3 vtkMRMLFiducialListNodes. 
Now by default a vtkMRMLMarkupsFiducialNode will be created when Create New is
selected.
Update the Markups module logic to detect node added events and add a display
node if not in batch processing, import or restore modes.
Updated the simple region growing segmentation help documentation to refer to the
Markups module.

Issue #3417

COMP: code clean up to unify setting the active place node

Added a utility function in the logic to set the active place node,
matching the get active place node id method. Call it where the
selection node was being accessed, and make sure that the testing
and setting of the ActivePlaceNodeClassName and ActivePlaceNodeID
are done only when there is a change and with the Reference call
so that events are triggered.
Added a test of the new SetActiveListID method.

BUG: Fix loading of MRC files

This commit reverts r22292

Commit r22292 updated ITK external project to explicitly
set Module_ITKReview and also removed the setting of ITK_USE_REVIEW.

Considering that since r22163, Slicer is built against the ITK release
branch and that commits deprecating ITK_USE_REVIEW have not been
back ported to the release branch, commit r22292 had the effect of:
  -> having an ITK built without module review at all.
  -> preventing the MRC IO plugin from being loaded
  -> preventing MRC file from being read into Slicer
