118663 jvonka: Merge from DEV/SABRE_JANV1 (part 1)
   File Folder API (PoC - experimental WIP)
   - relates to RA-613
   - initial file folder CRUD including
   - * list folder children (minimal info by default) 
       with sorting, paging & optional isFolder=true/false
   - * create folders or (empty) files
   - * get node info
       with id, name, nodeType, auditable props, properties (not sys:referencable), aspectNames, ...
   - * put node info
   - * put content (upload file)
   - * get content (download file)
   - * delete node (cascade for folder)
   - * support for well-known folder alias, -root-, -my-, -shared-
   - TODO add tests
