Update 0.8.0!

I've decided to actually adhere to semver in my project now!

This release doesn't actually change much, but I added a keyboard shortcut: hold ctrl to speed up the robot a lot. Also, your profile is now gzipped before saving it, making it 4-5x smaller.

While the game is in alpha (with a major version of 0) don't expect your profile to stay valid for long. Once I move into beta or whatever your solutions will stop getting wiped every update.
