Fix for multi-controller debug display.

Previously, multiple controllers in a single age
would overlap.  This adds a static positional
counter which is reset at the start of a new list.

This commit also attempts to make the list more
useful by showing the controller objects'
owner's name.

happening at runtime.

Ensure there is always book-spinning while linking

This should help people realize that things are happening... Even if
whatever server they're connected to takes a very long time to process a
join request. At some point in the future, the linking process should be
de-serialized.
