PlaceholderAPI (PAPI) support

[Folas1337]

I would find it super awesome if you could use placeholders of PlaceholderAPI within the frontend. That way I could display people's AFK or PvP status or maybe even their balance (obviously an almost unlimited amount of information could be displayed).

This would add lots of options to see even more data on the map at a glance, ideally on the player layer as well as in the sidebar :)

If you need an example or more information of any kind, let me know :)

@granny Any chance this might be happening or any response to it, like the probability of this ever happening? :)
