Added MySQL support! You can now connect multiple proxies with a set value in your database without having to enable maintenance on every single proxy by hand! Create a table with two columns, one named "setting", the other named "value", the config will do the rest!
Even timers will enable and disable maintenance mode on every proxy connected to your database!
The only downside is, that the whitelisted players will still be saved in the file on each proxy individually, but you could also just use the 'maintenance.bypass' permission instead.
Fixed a bug with the kickmessage not being displayed properly
Minor performance improvements
If you were using an older version of the plugin, you will have to delete your old config!
