[WIP / DO NOT USE ON PRODUCTION!!] Begin implementing support for SuperVanish and fix bugs

- Update dependencies in pom.xml
- Replace TotalFreedomMod's vanish system with SuperVanish. It's widely supported by many major plugins and does a better job vanishing players
- Fixed a typo in the SQL command for creating admin tables, where the table would not be created on a clean install of TFM
- Update bStats Metrics to latest version
- Remove the VanishHandler
- Sync the permissions.yml from whats on the server. Entries for Essentials and SuperVanish will be added soon

KNOWN BUG:
- Plugins override TFM commands (e.g. Essentials takes over /list instead of giving it to TFM). I noticed that there is a semicolon before every TFM command. (:/ban, :/list), which is the actual TFM command. I have no idea where / how this bug came from. Urgently needs to be fixed.
