+ The bank system is finished, when running /markets bank it will now open a GUI, you can use add as the 1st command argument to add items.
+ You can now withdraw custom item currency from the bank GUI
+ Added an add item button to the market edit and category edit GUIs
+ Added a rating system to markets, when viewing a market, you can leave a rating if you wish to. (1-5 stars, messages are optional).
+ Added a market upkeep fee, this is disabled by default. If enabled markets will attempt to charge all market owners every week (can be changed) a fee to keep their market open. If they are unable to pay that fee, their market will be locked. When a market is locked, you cannot view it, buy from it, take out items, or even add any.
+ Added the command "/markets pay upkeep" which goes along with the feature just stated, this will pay your market fee and reopen it.
+ Added the command "/markets force save" which will force save all the data.
+ Fixed an issue with the market help command, the length comparator was broken since a syntax message wasn't found.
+ Added MySQL support, you can enable the database settings in /markets settings
+ The add item GUI will now tell you that you have to select a category in order to add an item
+ If you don't have any categories in your market while trying to use the add item GUI it will tell you that you need at least 1 category.
+ The default market description message can now be translated.

And finally, fixed some minor bugs.
