wallet 0.3

Okay, wallet should now be fairly feature-complete for what we need for the initial release at Stanford. That unfortunately means that it only handles keytabs and only with the features of our old leland_srvtab system, so a lot of stuff is missing. But it's a start, and it means that we can start using it.

The neatest new feature is support for default ACLs, so that wallet entries can spring into existence as needed based on local site policy. I also added ACL integration with our NetDB host management system and support for MySQL as the underlying database engine, as well as better history, auditing, logging, and other things.

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