Remove $result passing $args by reference

from patrick: The big trouble I was having was that something was amiss when the plugin added the 'Internet Archive' tab to the top of the item edit pages--something went very badly wrong and all I got was a white screen.
I tracked it down to line 604 in BeamInternetArchiveRecord.php:
$result = fire_plugin_hook('beamia_set_settings', &$args);
It didn't like passing the $args by reference, so this worked fine.
$result = fire_plugin_hook('beamia_set_settings', $args);
Update README.md
