! Fixed importer support for MySQL 5.6+ (import.php)

! Making it clearer that the importer isn't under the Wedge license, but rather the New BSD license. I could have forced it, but Thorsten wrote 95% of it, and I don't feel I'm entitled to choosing a license for something on which I only fixed bugs and didn't write anything of importance.
