All stored procedures now work (as long as the database has been built,
populated, etc.)
Util.php updated as outlined in changelog.
Add and delete user not yet tested.

Nothing
Add PHP function alternatives to the stored procedures

Just in case we want to use this instead. It would be a lot easier and cleaner in the long run.
Clean up functions_mysql.php just a bit
Make functions_mysql.php into a semi-product-merged version of IO/Util.php

This reduces the code in the functions themselves, but makes them dependent on an outide mysql $link
I removed the connection checks because that already happens at link time in index.php
