// This looks for our specially encoded email addresses and replaces them with a simple mailto on the fly.
// The hope is that spambots run on the downloaded source, which doesn't contain the address, but a
// tenth of a second after the page finishes loading we will decode the email address so the user can click
// on it normally.
// The node should look like one of the following:
//		<a class="nospam" href="encoded_address">$$$$</a>
//		<a class="nospam" href="encoded_address">anything</a>
// The first form is where the visible text is the email address. The function changes both.
// The second form is where the visible text is not the email address. For instance, it could be "click here to email us".
// The encoded_address replaces the @ and the . with spaces. For instance, if this is encoded "me example com", then the address is "me@example.com".
