Updated code for PHP 7.0

It did turn out that mysql_connect and several other functions were deprecated between PHP 5.6 and PHP 7.0. I’ve gone through my scripts and updated them to use the new APIs that are supported by PHP 7.0 and reset the default back to PHP 7.0. Things seem to be working okay so far, and supposedly PHP 7.0 should give a significant speed improvement. We’ll see.
