Is WorldGuard 6.0.0 still using WorldEdit < 6.0.0?

Because the WG 6.0.0 source seems to reference stuff from com.sk89q.worldedit.bukkit which doesn't seem to exist in WE >= 6.0.0

Well, it compiles now: 7e8030a

Still trying to make sure I tracked down the last of the String -> UUID changes that are needed.

Waiting for this to hit the maven repo: http://maven.sk89q.com/repo/com/sk89q/worldguard/

Fixed

Seems to be alright.
