Searching Cards, Data Entry and *navbox+discussion

As for refining results, this is a key feature that has already been funded, and that we hope to deliver some time in November.  Because it involves some javascript work, we plan to do this alongside the rails 3 upgrade (wagn currently uses rails 2.3.11, but we have rails 3 mostly working in development).

As for the *navbox problem, there are currently issues whenever there is more than one navbox on a page.  That, too, will be fixed by wagn 1.8 (we're currently at 1.7.1).
