v2 Patch notes

First patch woohoo. Nothing major, just some small tweaks.

• Removed the quit button from the main menu as it didn't do anything but crash the game
• Reduced Fireball's size and damage
• Added 1 new enemy (thanks Ari for the suggestion)
• Added glossaries for looking at all the cool default godot icons in the game
• Tweaked BigRock's size scaling
