Added a Settings menu where you can adjust the parameters of pack rates and card spawning speed.

Fixed a major oversight where the common card distribution was being color fixed. It caused major inconsistencies with the card distribution in some sets.

Added a card back changer to the table. It's a little spartan right now, but to use it, place your desired cards to change in the black rectangle. Click the button and enter a URL then click "Change." Note that invalid URLs are not checked for right now so your cards will break if it's not valid.

Fixed major oversight bug where Spawn Booster Box simply didn't work.

- Fixed spawning being a little too fast for "Spawn Set." Eventually I will add configuration options for this.

- Added proper support for cards that require more than 1 unique token (like Wurmcoil Engine). Overall the token spawning system is a lot more robust than the previous version.

Added token functionality. Whenever the script spawns a card that has an associated token in the Scryfall API, it will spawn with that token.

Added functionality for dual faced cards. If a dual faced card is ever spawned by the script, it will spawn one that is dual faced and another with a normal card back and the front face only (for actually adding to the deck).
