ENH: Improved scripted module loading error message

It happened multiple times in our group that a developer spent a lot of time trying to find errors in a scripted module, simplify the class, make it more similar to the template, etc. to find what can be wrong in the class because "Failed to load scripted pythonqt module class definition" error was reported. Then it turned out that the module class is perfect, only the name does not match the filename.

Implemented fix: changed the error message to "class ... not found in file ..." to make it clear that the problem is not in implementation of the class but in the name.

BUG: Fixed DICOM browser persistence

If the DICOM browser persistent option is enabled (usually when the DICOM browser is displayed on a second monitor) then the browser should be kept open when an image is loaded or the user opens another module.
The persistent flag was observed almost everywhere where it was needed, except at the end of the image loading step.

ENH: Allow users to acknowledge all DICOM loading errors with a single click

Problem: Each DICOM loading error was displayed in a separate popup, which
 required the user to click as many times as many series failed to load.
In some cases there are a large number of failures (for example,
experimental MRI sequences), which makes loading of a complete study very
frustrating (need to click 30 times, waiting several seconds between each).

Solution: Changed the error reporting to collect all errors and show it to the user at the end of the loading in a single error popup.

ENH: Subject hierarchy module added

This is the first step of integrating Subject hierarchy into Slicer core.
Next steps include moving subject hierarchy plugins to their related
modules and making DICOM import plugins add loaded objects in the
hierarchy.

ENH: Node attribute table view and widget moved to MRMLWidgets

qMRMLNodeAttributeTableWidget, so they have been moved from Data module widgets to MRMLWidgets

ENH: Moved core module subject hierarchy plugins to related module

Subject hierarchy plugins project contained plugins for core modules
Markups, Models and Volumes. Those plugins are now in the
SubjectHierarchyPlugins subdirectory of those loadable modules.
Also the subject hierarchy support moved from
SlicerRT/DicomRtImport/DicomRtImportPlugin.py to
DICOMScalarVolumePlugin.py. Now the loaded DICOM scalar volumes are
automatically added to subject hierarchy.

ENH: Sank addSeriesInSubjectHierarchy function down to abstract DICOMPlugin

The addSeriesInSubjectHierarchy function (which was in DICOMScalarVolumePlugin so far) adds
the loaded node to subject hierarchy to the proper patient (subject) and study according to
the DICOM tags from the first file referenced in the associated loadable. This function is
now accessible from all the DICOM plugins. It needs to be called after the loaded object is
created in the load() function. Now it is called by DICOMDiffusionVolumePlugin too.

ENH: MRMLCLI_INCLUDE_DIRS CMake variable exported

ENH: Subject hierarchy python tests moved to SlicerApp

As the subject hierarchy tests cover multiple modules, they have been moved

COMP: Moved subject hierarchy base plugin classes in widgets

In order to subject hierarchy plugins be accessible from extensions,
the include directories need to be exported. So that the current
infrastructure can be used, all subject hierarchy plugin
classes (abstract, handler, core plugins not related to modules) were
moved from Plugins to Widgets. Plugins subdirectory thus became
unnecessary and removed.

Subject hierarchy widget designer plugins were deployed to Slicer_DIR/bin,

BUG: Fixed subject hierarchy core plugins self test

Which failed due to renaming of GetAssociatedDataNode to GetAssociatedNode in
vtkMRMLSubjectHierarchyNode. It has been renamed, because by making
vtkMRMLHierarchyNode::GetAssociatedNode virtual, it became possible to override
it in subject hierarchy so that it can handle nested associations.
