Version 1.0 Official Release

Introducing Version 1.0! Featuring the last three playable ships and a major bugfix!

• Igor: an asymmetrical ship with 2 different weapons. Upgrades and second weapon change with ship mode. Choose from a shotgun, burst gun or a death beam!
• Krill: an unusual ship that uses bubbles for attack. Upgrades focus on making the bubbles dish out more destruction.
• Santa: a jolly old man bringing the gift of pain to space. Upgrades are changing his main weapon's functionality or launching exploding presents in an arc.
• Fixed enemy collision at low speeds. Now you will properly take damage from slamming into any enemy. Apparently it's a known issue with the latest version of Godot and the previous version didn't have it, so I just downgraded since I wasn't using any new features anyway.

With that, the game is completed! Let me know in the comments if any bugs pop up and I'll fix 'em.
