Add a timeout when connection is open without any result for longer than 6 seconds. (Crash prevention)

You can now blacklist IPs that start with a specific prefix.

Here's an example:
/pvpn blacklist add 0.0.0.*
> This means that IPs starting with 0.0.0.*, such as 0.0.0.1 or 0.0.0.3, will be detected.

Another example:
/pvpn (bl/wl) add 0.1.*
> This means that IPs starting with 0.1.*, such as 0.1.34.124 or 0.1.44.214, will be detected.
> On the other hand, IPs like 0.6.12.232 won't be detected
> because they don't have the same starting point.

Shortcuts for easier command usage:
- blacklist => bl
- whitelist => wl
- clear => clr
- list => ls

New messages:
"Clear-Failed" message for white- & blacklist!
=> When someone clears the black-/whitelist and there's nothing in the list, it will respond with the message "...-list is already empty!"

Just implemented the support for further 1.20 server versions! ^^

PLEASE DELETE THE OLD CONFIGURATION FILE!

New design:
- Improved Discord webhook message
- More options for Discord webhook configuration

Bug fixes:
- Fix the wrong update message at the join
- Fix missing auto-complete for reload-command
- Set default configuration for console-ban-command to false
- Reload Discord webhook configuration on reload-command

Fixed that the plugin won't load on Bungeecord servers!

The Update-Check had some troubles in the code and I've implemented an ingame message to notify an operator player if a newer version of the plugin is online! ^^

I've implemented bStats to get a small statistics number of users using this plugin. This is anonymous and can be disabled here:
