every unique item expands the border

Creator notes

I saw this in a youtube challenge but couldn't find the download, so I remade it better. works with all items, even ones from mods made after I die! when any player discovers an item, the border expands by 1 block and they get an xp reward. when any player gains xp, the world's xp also increases. when the world's level increases by 1, the border expands by 1 block and the player gets an xp reward. you can configure how much xp the world gains: 0 to disable with /scoreboard players set #eb_xp_ratio eb_score 0 100 to normal, don't recommend setting this over 200 and past some high setting the xp from this will level up the world infinitely.
