handle very looooong urls+solution

For now I think we just want the parts of these long urls to be hidden so they don't go careening into nowhere land.  It is very difficult to make them wrap well, especially in a resizable site like a wagn.

FWIW, I think it's also not great interface to show long urls to the user at all -- generally much better to put the whole url inside the link and shorten the readable text to the domain or some other text.
