Improvements:

• Locale System improved, easier to add new messages - Web pages are now translatable through the Locale, so no html changes are necessary.
  • If you have an old locale rename 'Cmd Usage -' to 'Cmd Help -'
    
  • German locale by @Morsmorse
  • Partial Simplified Chinese locale by 佛壁灯 ( @f0rb1d )
    
  • Finnish locale by me
• HikariCP Replaced DHCP2 with HikariCP as connection pool (Bukkit, Bungee), should improve fetch speeds
  • Connections now validated before use to reduce exceptions
• Database Patching Now patches are applied if they are not already applied, this means if you skip multiple versions in the future, all database patches are applied. Failed applications are also re-applied with this version (Looking at you IP anonymization)
  
• Connection System Replaced bare java HttpUrlConnection with Apache HttpClient that has more reliable API in terms of closing resources (No more thread leakage)
• Font awesome update 5.0.1.3 -> 5.2.0, Thanks to @Argetan
