1.14 support.

Spigot stopped supporting TravelAgents in portal events, limiting our ability to detect portal exploits. We are no longer able to check if a portal being created in a location is by a member of a faction. Because of this, on 1.14 and newer, we will block all portals created anywhere but in wilderness. On older versions, we'll still load up the old way of checking this, but in a legacy listener.

+
+    The options are:
+    1. PlayerPortalEvent, which doesn't let us know anything about the portal so we can't stop a player from
+    creating a portal at a location they aren't allowed to.
+    2. PortalCreateEvent, which doesn't give us any information about the player that makes the portal, so we can't
+    stop specific players from creating portals in Faction land.
+
+    So for now, we'll temporarily block ALL portals from being created in anything but wilderness.
+    Spigot mentioned that TravelAgent might come back, so we'll leave this commented out here for now.
