Fix 'allow_url_fopen' error

dleffler

A way to remove the '...disabled in the server configuration by allow_url_fopen=0' error message when attempting to display an external calendar, twitter feed, etc...  Add the following to the middle of your /overrides.php file (between the opening <?php and closing ?>

ini_set("allow_url_fopen",1);

As a note, in versions after 2.3.7 we will no longer ship an 'overrides.php' file since it is auto-generated during an installation if needed, and it is where we encourage users to place there site specific settings..therefore we shouldn't overwrite it.  There is a sample file found at http://downloads.sourceforge.net/project/exponentcms/Samples/overrides.php
