You can now add as many lines as you'd like to your kick-screen message!
You can delay the amount of time until the bypass message join message is sent.
Code Changes:
Added a file which saves the state in which the server's maintenance status is in (true or false). This fixes the horrible system I used to store the maintenance status before.
Changed the kicking of the player. It will now kick the player before they even get a chance to join the server (using the PlayerLoginEvent instead of the PlayerJoinEvent which I used before.)
Lots of fixing in the code. I coded v1.0 a long time ago, much before I knew a lot about Spigot Development so a lot of the code was really bad lol
