Permissify

Fixed - Chat help for group create - General help formatting - Better checks when doing actions on a player - Overall better error responses on many commands - Group create command not working sometimes Changed - sqlite is now the default connection type instead of mysql - Changed superadmin command usage. See the Added section for more information. - setmain to primarygroup Added - /permissify superadmin grant <name> and /permissify superadmin revoke <name> - Support for 1.13. Permissify is tested to be working on 1.11, 1.12, and 1.13. This includes all versions in between as well. Optimizations - Optimized the use of PermissionAttachments. This gives us lower memory usage overall, and minor speed improvements.
