CANs link command should enumerate links for the named note

When called with a valid note name as an argument, the CAN link command should enumerate links for the named note.

The link-rendering handler should listen for the COMMAND_LINK event and render the correct list of links. Each link should be on a separate line. Each link should have the link title text and the URL.
