-Subject: [PATCH] ExperienceOrbMergeEvent
-
-Has to be reimplemented at one point maybe
-Fired when the server is about to merge 2 experience orbs
-Plugins can cancel this if they want to ensure experience orbs do not lose important
-metadata such as spawn reason, or conditionally move data from source to target.
