EssentialsX Discord: Custom message types using regex.

[SoyaNyan]

I suggest adding settings for custom message types using regex.
So some messages can be filtered and sent to each discord channels.

I found someone asked adding more message types like 'Jail' or 'Gamemode'.
(Essentials Discord "message-types" #4858)

But I think this way is better than adding every single types that user wants.
