Fixed: Region and Warzone checking. (Found by @Sallinx)
Added: /rankquest redeem when you do /rankquest to see the commands usage.
This update fixes region and warzone checking. Now regions and warzone are given equal priority. If a player is either in a whitelisted region or warzone, the quest will work. If blacklist is turned on, the quest will work when the player is either in a whitelisted region or warzone, and when he is NOT in a blacklisted region. If pvp flag is enabled, it will be required for the quest to start as well.
