Update jquery.min.js

The official jquery.min.js version 1.11.1 does not include the source mapping comment at the end so neither should the mirror.

http://code.jquery.com/jquery-1.11.1.min.js

On their download page they specifically state that it will no longer include this line after 1.11.0. Recent versions of Firefox complain about this.

> As of jQuery 1.11.0/2.1.0 the //# sourceMappingURL comment is not included in the compressed file.
