[0.24+] Duck's dubious tweaks to xp gain 1.0.0

This mod does partly work for 0.23 as well, the only problem is with the great weekend buff, if you have it the game will complain about it and won't apply it. But if you don't get that everything else should work as intended.

So, this mod does quite a few things:

-Changes hidden achievements to give a 2% xp boost instead of 1%

-Changes the quicktime minigame to give a 2% boost to xp instead of 1%

-Halves the weekly decay of the quicktime minigame bonus

There shouldn't be any issues with other mods unless they also change those things. It should work on 23.6 and the current playtests as well
