[Seaside] callback registry

With the model of Seaside, it is hard to tell what callbacks are still
used when doing AJAX. Therefore I suggest to do a full refresh from
time to time.

Note that you can easily do a full refresh through AJAX. Just trigger
an AJAX request to a normal callback, extract the string between
<body> and </body> and place it into the DOM tree. This recreates all
the callbacks in the page and ensures that old ones eventually expire.
To the outside this "full request" feels like a normal AJAX action,
just that it is maybe a bit slower than the other ones.

Actually I planned to write a blog entry about this technique, just
didn't find the time yet.
