EssentialsX-Discord placeholder {SHORTWORLDNAME}

[MineTim]

Hello,
this feature request is about the EssentialsX-add-on for Discord.

When I use Essentials Chat, I can use the placeholder "{SHORTWORLDNAME}". This placeholder returns the first letter of the world, e.g. world "Farm" returns "F". I like this feature and I want to use that in the discord add-on.
At this moment, there is in "messages:" in the section "mc-to-discord" no equivant placeholder. Is it possible to add this? :)

(I saw #4416 already - there stand, that this will be added in #4419, but it seems that this is not added...)

Regards
MineTim
