Create CMS concept for WAVE

Need to have CMS functionality for portals.
Base on virtual file system - revisions - approve/unapprove by content admin.
Basically a catalog of structured resources: files, configs, NLSmaps, menus
and page templates . tbd email templates

The CMS design is to be based on VFS.
The ui CMS manager will just work with version controlled solution a-la Git, we will pull and cache resources using Pile for instantaneous access in-ram
