What's been done:

• Updated compiler versions
• Updated Hikari.
• Added built-in Vault support, this can be enabled in the config file. It is disabled by default.
• Added Update checker, do not worry! This won't spam your ingame chat. It will only print a message in the console when the plugin is loading.
• Added Metrics, just because I am curious over how many servers is running this plugin.

Note:
The custom vault version is no longer needed, please if you used it, add the original vault version back in case of inconsistencies between them.
