fly command no checking permission after map change.

CMDBOOK-2269 - Reported by RustyDagger

The title pretty much explains it, Currently if you enable fly in a map where you have permission then change map to where you don't have permission you can still fly. surly bukkit provides some way to detect a map change and acting on that would only be trivial. I am sure there are many server owners that would much like to have /fly usable on a player level much like I would. its nice to have on a building map but exploitable on a pvp level.

if the above cant be done can some kind of non toggle command be added to allow me to force it off using a command block currently i can only run /fly on a player and that could either turn it off or on.. maybe /fly name off

Start by reproducing the reported sequence: enable /fly on a map where the player has permission, then change to a map where they do not. Review the Bukkit-related command and map-change handling, and consider the report complete when flight is no longer retained across the permission change or the requested explicit off behavior is clearly defined and tested.
