Did full plugin recode, just some base code staid same or changed/fixed little bit to be more professional
Changed entirely how commands are processed
Changed how locale file are processed, so now you can have separate files for different locale
Put recipes into separate file
Config file rewamp. In general your old configuration should stay same. Now there will be nice comments before each line to give some basic info what it does
Changed command from /bottle [amount] to /bottle get [amount], this is because now by typing /bottle will give command list with explanations how to use them
added option to craft custom exp bottles with custom exp in them. Currently you will need to put glass bottle into crafting station and you will get option to craft bottle containing all of your current exp. After crafting you can consume it by right clicking it while it in quick bar. (this was requested as new feature)
Added experimental option to disable trading exp bottles with villagers. tested on 1.8.8, worked fine, need some testing on older version. Use with with your own risk.
