Modified how links are created so that the caller must specify a link type when the link is created, rather than setting it later. This was done to avoid having to send two link data packets following the way links would be handled logically. Turns out this was good idea overall for ensuring link integrity, because there was one case where I forgot to set the link type after creating the link.
