Fixes missing semicolon in minified plugin.

[abeisgoat]

This missing semicolon causes an issue where jQuery may be undefined in the minified version due to the script being ran before your jQuery.js is loaded. This is not an issue in the non-minified version because the semicolon is present. This will probably require a change in your minification configuration to prevent regression :)

Actually, no. That doesn't solve that, it's an unrelated issue. Should the entire plugin be wrapped in a (function () {...}()) to solve this?
