- link actors into blockmap through linked line portals.

Browse source 
Links through sector portals are not done because nearly all the checks can be performed without doing this so if it works without there's no need to add more processing time.
Will have to see if there's cases left where such a link is needed and if so, whether there's better options to do it.

For line portals such links are necessary to have proper collision detection with actors that are currently transitioning the portal.
