BUG: fix leaks on scene close - related to issue #2512

Use vtkSmartPointers to rather than bare C pointers
to manage lists of node references.  This avoids dangling
pointers to already deleted nodes (and hence prevents
crashes).

Also STYLE: add at least some documentation to the header
file describing what these methods are meant to do and
how the data structures are managed.

BUG: Apply redesign to glyphable volume slice display nodes

In r20910, model display nodes had a demand driven pipeline redesign.
However, this redesign wasn't applied to glyphable volume slice display
nodes.

BUG: Restore 2D slice glyph display

When display nodes where added to a volume node,
vtkMRMLVolumeGlyphSliceDisplayableManager was not notified so it couldn't
observe the glyph diffusion tendor display node modify event.

BUG: Update display when tensor display properies are modified

When the properties node is modified, the event must be propagated so that
the 3D and 2D displayable managers are notified and trigger a refresh.

BUG: Move light box renderer manager proxy to abstract displayable manager

Suggested by Steve Pieper
Contributed by Jim Miller

Moved the LightBoxRendererManagerProxy up to the superclass of the
DisplayableManager hierarchy so that all (2D & 3D) displayable managers
can interact with a lightbox.

Note that light boxes are only currently supported on 2D viewers, so the
proxy is only configured in qMRMLSliceView. CTK will need to be changed to
put the LightBoxManager into ctkVTKAbstractView to make it accessible to
both ctkVTKSliceView and ctkVTKRenderView. Then qMRMLThreeDView could also
create and initialize a LightBoxManagerProxy and set it on its DisplayableManagers.
Here, we would also want to move qMRMLSliceViewPrivate::vtkInternalLightBoxRendererManagerProxy
class to a place where it could be used by both types of VTK widgets.

The proxy can now be set on the DisplayableManagerGroup which
broadcasts the proxy to all the DisplayableManagers in that group.

BUG: Disable ITK_AUTOLOAD_PATH/itkMRMLIDIOPlugin for executable CLIs

Unset ITK_AUTOLOAD_PATH environment variable to prevent the CLI from
loading the itkMRMLIDIOPlugin plugin because executable CLIs read images
from file and not from shared memory. Worst the plugin in the CLI
could clash by loading libraries (ITK, VTK, MRML) other than the
statically linked to the executable.
Historically, there was an nvidia driver bug that causes the module
to fail on exit with undefined symbol.
