Also catch wrong types when loading the config better without completely disabling the plugin and revert "Make sure special parsers are setup" and register the parsers static again.
Also add tax bypass permissions (#204, ChestShop.notax.buy/sell). When buying with that permission the buyer does not have to pay the tax (the seller will still get the reduced amount), when selling the seller will get the full amount instead of one lowered by the tax.
The permissions of the shop owner play no role due to there not being a good way of checking offline player permissions and it being a bit non-obvious for the buying/selling player if a shop would be with or without tax. This way all that gets changed is the amount the player pays/receives and not the shop owner (and the player should know their permissions/rank already)
The transfer event was necessary in order to correctly resolve who triggered the transaction. Economy adapters are now required to implement a listener for each of the events. It's also recommended that economy adapters that support transfers directly use that instead of passing it through subtract and add with the processTransfer method.
This is necessary so that we still store the messages with the & code internally as they would get saved back to the config file using the converted color code (section sign) which could lead to encoding issues on different operating systems. (It also fixes issues with strings that contain an and sign that isn't supposed to be a color code) Instead we load the real string and color messages via the prefix method which should get called in every instance where a message is send.
