Fixed bugs with Line_PortalSetTarget and added more portal geometry warnings

Browse source 
- A bug exists where portals that have been deactivated with Line_PortalSetTarget cannot be reactivated, even if given a valid target.
- Another bug exists where portals that were created in an inactive state (using a target line tag of 0) could never be activated. (Even with the above bugfix.)
- Linked portals that have been demoted to teleport portals because they do not have a return portal now emit a warning.
- Portals that are supposed to be traversable, but do not have back-sector now demote to visual portals and emit a warning, because nothing could ever possibly traverse them anyway.
