The permission check for rendering/using an editpanel in the frontend for logged in backend users depends on the BE user's permissions for the current TSFE->id only.

This may lead to non editable records in FE for logged in BE users, although they actually would have the permission to edit those records in the backend.
Which is I think a major drawback for FE editing.

That is typically (but not only) the case for FE plugins with their records being stored in a sysfolder, which shall be editable for some BE user but who is restricted by permissions to edit the page where the records are eventually outputted in FE.

The attached patch introduces a new parameter for cObject EDITPANEL and stdWrap property editPanel named
permissionCheckOnPid = [int | keyword 'pid']
for checking this editpanel's usability/permissions based on a given pid (if an integer) or a record's pid field (if keyword 'pid')
