IE css styles are missing

Dear Mihaela,

thanks for the great work on the fancy box plugin.

Accidentally, I discovered a missing CSS file in the repository for IE css styles, which results in a HTTP 404 and most probably displaying issues when using Internet Explorer as browser. Probably, the file needs only to be added to the repo to fix this issue.

Issue
=====
You register a specific IE css style in
fancybox.php:171, but the file is not present.

wp_register_style( 'fancybox-ie', FBFW_URL . 'assets/css/fancybox.ie.css', array( 'fancybox' ), '1.3.4' ); // Main Fancybox style fixes for IE6-8

Solution
========
Please add the missing css file to the repo.

Thanks in advance,

Matthieu
