Changes:
- Added 1.18 support
- Added the ability to add essentials colours to clan names
- Changed saving behaviour to reduce IO usage (saves every 15 minutes)
- Changed [code single]/clan[/code] command to be a default command
- Added supported version checking (1.13.x, 1.14.x, 1.15.x, 1.16.x, 1.17.x, 1.18.x - Not all version have been tested but should be okay)
- Improved start-up and shutdown behaviour

Known issues
We are currently aware of users not joining the correct clan and incorrect clan prefixes being shown. We are currently reworking the storage side of the plugin and migrating away from JSON in favour of YML and MySQL for more advance users.
