Path by type bug!

[mathisono]

Backbone links are not being sorted by type into BB but rather they are all being sorted into OTHER, along with Wire Guard tunnels. Looks like the the TYPE TUN only holds legacy tunnels!

IIRC, the KML code has a short list of link types hard-coded in it, and I think it was written before the new link types became available. So that list and the code handling it needs to be updated.
