XML

This PR brings parsing of GL3.txt into an XML file, to reduce processing strain on page generation and for later added benefits like feature implementation time. Unfortunately at this current time the commits list at the top of the page and the separate footnotes section have been removed.

Include files (.inc.php) have been removed from http, so that only web server required files exist in that directory. `config.inc.php` now exists in the root directory, while `oglparser.inc.php` and `commitsparser.inc.php` are moved to scripts (although `commitsparser.inc.php` is not in use currently).

The authors section at the bottom of the page now uses data stored in `config.inc.php`. Authors can now have a website associated with them. Likewise many other variables have been de-hardcoded (softcoded?) to `config.inc.php`.
