v1.0.6 live!

A much needed update, promised long ago.

• Added keyboard remapping! Yippee! Hooray!
• Adjusted the overall game difficulty to be more forgiving, especially in the Switcher Mode.
• Changed the ring spawning logic to make them appear in more predictable and fair locations.
• Disabled keyboard controls entirely in multiplayer mode.
• Made the glow effect on the cows and corns a bit more subtle.
• Made the screen shake effect slightly stronger when you get a ring with a level 4 ship. Like, very slightly stronger. This is how through I am being with these changelogs.
• Made the menus feel more responsive.
• Improved the transitions used in the options menu.
