Put confdir in the params class, and more..

Fix a bunch of warnings whne using the bind::updater class by moving confdir to
the params class. In order for this to work, the bind and bind::updater classes
both now inherit from params. Also, fix the default value for
managed_key_directory to something that's actually falsey.
