Fix docs.jquery.com links

[jzaefferer]

There's a bunch of links pointing at docs.jquery.com, like this one:

api.jquery.com/entries/ajaxComplete.xml

Line 10 in 69ed47a

<desc>Register a handler to be called when Ajax requests complete. This is an <a href="http://docs.jquery.com/Ajax_Events">AjaxEvent</a>.</desc>

Should be a relative link to the right page.
