This update adds support for more currencies apart from the default vault. For now it only support gemseconomy but on the next updates more plugins 'll be supported, if you have any plugin request feel free to add it on discussion. Also this updates fixes the bug that made versions <1.12 to crash

• Added multi-currency support (gemseconomy)
• Fixed bug on <1.12 which caused the server to crash
• Optimized code
• Made internal database thread safely

Also a new option was added on the config and some new other options on locales, i suggest to delete them and let the plugin regenerate the files
