BUG: Volume visibility controls for subject hierarchy fixed.

The visibility controls did not work well in subject hierarchy, now it is fixed. Also fixed bug when importing scene: due to the automatic subject hierarchy node creation duplicate SH nodes were created when scene was imported. Simplified DICOM object naming in subject hierarchy: the name of the loadable is used instead of assembling the very same name from the same tags.

Fixes #3893

ENH: Add generic folder plugin to subject hierarchy

The new plugin allows the user to create arbitrary folders, instead of the fixed hierarchy of levels. Also now patient and subject nodes are strictly separated.

Fixes #3898
