Subject: expose manual public item import from searchbar, set commen_policy in
 Activity::store() to what we get if we get something otherwise default to
 authenticated, comments by the owner have the relay flag set and therefor
 $perm will be not be set to post_comments - always check if we own the parent
 in lib/libzot (not only if $perm = send_stream) if otherwise not allowed
