Custom controls

It's been a while, I'm back from holidays and game jams and stuff. I didn't have a lot to do to finish this update (most of it was made by pre-holiday past me, thank him a lot).  Also I certainly did not just spend 75 minutes on a bug that showed when testing in browsers but not locally.

Anyways, the game now supports customizable keyboard controls!

That's pretty much it. Now you can map keys however you want and stop suffering because you're used to jump with spacebar. And by the way, you may use the same key for jumping and swimming up, but it's the only actions that work this way.

Controls are saved locally in the same way unlocked/completed levels and best times are. Default controls are arrow keys, up arrow to jump, space to pick up/drop, c to dash and p to pause. 

I also fixed more bugs on the help screen like being able to move the characters used in the cutscenes, which was rather wacky. 

I'm not sure what I will work on next-aside from the usual bugfixes, I want to try improving the looks of the game. 

Have some fun!
