wallet 0.4

Well, today was mostly a loss, but I did finish committing some changes I'd been planning on doing for quite a while and getting a new wallet release out that fixes some oversights in the last release. This release should be good enough for internal testing at Stanford, although I still need to write an administrative interface for setting it up in the first place and doing metadata operations.

The main change in this release is my realization that I had no way of combining NetDB roles with root instances, which made them useless for my own group. Doh. But fixed now.

You can get the latest version from the wallet distribution page.
