Global placeholderAPI support

make the placeholderAPI compatible across the plugin, many players use MULTIARENA mode, and your lobby scoreboard doesn't fully support the placeholderAPI and that sucks, maybe it would be better not to have this scoreboard at all

apart from that if you use a tag/prefix plugin, it will only be possible to show the player's tag/prefix through the vault, which becomes terrible when using luckperms
