+Subject: [PATCH] force entity dismount during teleportation
+
+Entities must be dismounted before teleportation in order to avoid
+multiple issues in the server with regards to teleportation, shamefully,
+too many plugins rely on the events firing, which means that not firing
+these events caues more issues than it solves;
+
+In order to counteract this, Entity dismount/exit vehicle events have
+been modified to supress cancellation (and has a method to allow plugins
+to check if this has been set), noting that cancellation will be silently
+surpressed given that plugins are not expecting this event to not be cancellable.
+
+This is a far from ideal scenario, however: given the current state of this
+event and other alternatives causing issues elsewhere, I believe that
+this is going to be the best soultion all around.
+
+Improvements/suggestions welcome!
