Subject: Move Commands stuff out of classes

The classes/ subdir is primarily for the DB_DataObject classes. Stuff
in there can get stomped by various generation scripts.

I've moved the lurkers there -- related to command-handling -- to
lib/. Since auto-loading works fine with lib/, there shouldn't be much
of a visible change here.
