Update 4.15

This Update changes the "version check" and adds changelogs, the legacy "version" file will be used until ~2 months in the future.

EasyAdmin now displays some rudimentary player informations when spectating
We fixed some issues with the 'strings', there should be less formatting errors now
we changed the queue up a bit, report back how it behaves now!
player list should now sort by first joined rather than seem quite random.
