Minor URL Typo in PHPExcel Documentation

[preichow]

This is such a minor bug that I almost don't want to bring it up:

On page 6 of the PHPExcel Developer Documentation, there's a minor typo in the URL for the English PHPExcel tutorial in section 2.4.3 Tutorials. The URL is listed as http://openxmldeveloper

That website actually has a .org on the end.
The proper URL is http://openxmldeveloper.org

Fixed, thanks for pointing it out
