Fixed jQuery error

Hello!  Thanks for the great plugin.

Using YOURLS version 1.7-alpha and the latest of this plugin, I found that I get a Javascript error and the "Show descriptions of these terms" link (on the plugin's settings page) is not functional.  Although I have not verified, my guess is that YOURLS jQuery version was upgraded, causing an error upon calling the live function.  Rather than complain, I figured I'd fix it!
