Trash Can UI. Table to be reimplemented.

Append ?w=1 to the URL to ignore the trivial whitespace differences.
Think about reworking so that the caught.getMessage() is sent to the view, and the view shows the error in an alert in the page (along with a button to reload?). Currently you always pop up an error, and I would guess this page looks fairly empty after clicking OK on the error dialog.
