Additions:
- Players can now store their data with a MySQL database, it can be enabled at config "database.enabled" (disabled by default)
- Database URL, USERNAME, PASSWORD, and USESSL can be configured at config.yml
- If disabled, players data will be stored locally and will not be transferred between servers
- Command "/ew help" is now supported
- Added optional kit cooldown. Can be customized in config.yml with 2 fields: "kits.EnableCooldown" and "kits.SecondsOfCooldown"

Changes:
- Removed debug command "/ew stats". It wasn't meant for the plugin but something similar will be introduced in the future.

Fixes:
- Some old code cleanup
