-Fixed issues when using the item with Jacob and Esau
-Added Item tags

-No longer rerolls high quality quest items like The Polaroid
-Now works in multiplayer and for J&E.
-Because the reroll method is no longer recursive, the chance to reroll high quality items is now higher.

Slightly fixes the issue with items not rerolling properly
I used a completely different method of rerolling items, because the previous method kept crashing the game, and when I fixed the game crashes it broke everything else and stopped it from working at all.
The new method however, only works for the first item to appear in the room. So, if you reroll the item with D6 the item won't be any more likely to be trash. Also if you use Mystery Gift in a room that already has an item, the new item won't be more likely to be trash.
Furthermore, it only works in a room that you haven't visited before. On the upside that means it doesn't continually reroll the item when you exit and reenter a room. On the downside it won't reroll boss items if you teleport out, and reenter. Also, for some reason Glowing Hourglass doesn't undo the FirstVisit variable... because potatoes.
However, despite all these issues, the new method actually works and does the thing its supposed to. In the future, I might try to fix all these issues, but Isaac Modding is a giant pain and I have school and job to focus on.

-Should no longer crash the game when you get the item.
-Attempts are made to make the dmg ups approximate how they work in game.
--Now gives a slight soft cap to the dmg ups.
--Dmg ups are now smaller when you have items like Soy and larger when you have items like Polyphemus. It doesn't perfectly emulate actual Isaac dmg ups. But it's closeish.
-stat ups no longer apply to quest items like Dogma or key/knife pieces.
