Update loadmodule.php

Loadmodule does not support htmlspecialchars when passing a title.  This is
because the article is saved with htmlspecialchars.  The module title needs to
be decoded before matching.


<<< plugins/content/loadmodule/loadmodule.php:line 100
$name   = trim($matchesmodlist[1])

>>>
$name   = htmlspecialchars_decode(trim($matchesmodlist[1]))
