Nauseating teleportation and bigger portal frames

TODO

-* Detect a glass frame being placed
-* Detect a glass frame with a mineral block
-* Transform the glass frame to stained glass
-* Test portal block teleportation interruption
+* identify and pair portals by type/color
+* save portal pairs to disk and reload them on restarting the server
+* deactivate most recently placed portal and replace with newly placed one when 3+ portals are created
+* teleport from one to the other a set time after entering a teleportation chamber and closing the door
+* automatically open the door after effects wear off
+* close the door on the other side when someone shuts the door
+* teleport everyone inside the portal, not just the person who closed the door
+* interrupt teleportation if portal is destroyed mid-teleportation
+* save any effects that would be overwritten by teleportation (including to disk!), and put them back when the player opens the door or arrives
