Update 0.2

WARNING: if you have any demos saved from version 0.1, they won't play right on 0.2 and older! (There's currently no way to playback demos without decompiling and modding the game, but there will be later)

This update changes how demos are captured and played back. The reset is also much better now, also resetting any dynamic values the car has, and not just its position and velocity. This should help with improving playback consistency.

I tagged this devlog as a major update because a) it's a breaking change, and b) it's the first devlog and I think it'd be nice to post it like that
