Update 1.5.0:
+ New serialization technique, all data from an item should now be saved
+ Economy balances are now saved
* Fixed a couple bugs with 'setworlddefault' command

The way of saving and reading inventory data is now very different, but don't worry! The old way of doing it is still present in order to read the old legacy data. This means that you don't have to worry about converting it!

Update 1.4.0:
+ Separate saved inventories for each GameMode
+ Player inventories are now saved when they log off
+ Add some informational messages on startup
* Fix import bug from MultiVerse-Inventories; saved data in an incorrect format

Hotfix 1.3.1:
* Fixed typo in command help display
* Fixed crafted banners throwing an error

Update 1.3.0:
+ Default inventory loadout for each world group
+ New handling for banners, which correctly preserves patterns and colors

Update 1.2.1:
* Fixed bug where wrong gamemode was being applied

Update 1.2.1:
* Fixed option for saving gamemode not existing

Update 1.2.0:
* Rewrote ConfigManager. No visible changes to users.

Update 1.4.0:
When updating to this version, your worlds.yml file will automatically be updated to the new format.

If the plugin is running, and you set 'separate-gamemode-inventories' to true in your config.yml you must restart the server. This is due to the fact that I only register that Listener if that option is set to true, and I have found no good way to see if a Listener is already registered or not.
