- User and Group has been moved to 'models' directory
- removed UserPass struct (passwords fields were put to User struct)
not working yet, we need support for binary blobs in morm
- field(...) methods from Model take now FT structure instead of insertable/updatable/primary_key boolean flags
- table name is set in a prepare_table() method now
- added meta and admin_meta from ItemContent (morm has a field() method with PT::Space argument now)
and added ItemModelData (based on morm::ModelData) class which has 'prepare_unique_url' field,
an object of this class is passed to update(), insert() and save() methods
fixed: Dirs::CheckRootDir(): update should update childs too (privileges)
