EssentialsX support

[Eufranio]

Latest versions of EssentialsX aren't working on 1.7.10 Cauldron servers, and the devs said that it's a issue with the server software:

EssentialsX/Essentials#868

The error:

Don't write FUD - EssentialsX/Essentials#868 (comment)

@spannerman79 Either way, the event should have been implemented before 1.8, and since Thermos seems to be the only maintained Bukkit 1.7 implementation, it seems like it would be a good idea to implement this. Spigot implemented this in an NMS patch IIRC.
