Updated the sprites of the following symbols:
- Coin
- Dog
- Pearl
- Anchor
- Key
- Present
- Coal
- Big Urn
- Coconut
- Coconut Half
- Orange
- Midas Bomb
- Magic Key

- Updated the preview image to match the sprite changes

Most of the changes made were just some shading and color adjustments, with some changes being more noticable then others

- Removed basically all the individual scripts in favor of using literally just one
- Doing this also helped the game not freeze upon opening up the drop down arrow, so go disable the symbol resprites you didn't like to your hearts content!
