Log Message:
-----------
PFAHandler:

Add $can_edit and $can_delete flags. This makes it possible to make 
some, but not all items non-editable or non-deletable (based on a 
database column/query or read_from_db_postprocess())

- add $can_edit and $can_delete
- after initStruct, check if $struct contains _can_edit and _can_delete.
  If not, fill with default values (allowed)
- init(): set $this->can_edit and $this->can_delete (only in view/edit mode)
- set(): abort if !$this->can_edit
