New advancement "Overachiever"

New advancement called "Overachiever" the condition for getting this would be to get all other advancements except for itself. This would be the absolute final challenge that the game gives the player. It would either be within it's own self contained section of the "advancement tab" or within the Minecraft section. One would be given a bunch load of experience. You could also include some type of message to the player like the End poem by Julian Gough given when exiting the end after killing the ender dragon. 

Alternative name:

● One for the Books
● One for the blocks
● All Done?
● Game over?
● Journey's End (terraria reference?)
● All Boxes Checked
● Top of the mountain
● No Stone Unturned
● The End!!!

It was fun coming up with these, feel free to come up with your own!
