The player component hold information which should stay persistent
across the game-runs and thus needs to be passed through the different
game-states.  Do this by instanciating it in the heaven and then passing
it through the level-loading state into the in-game state.

Small cleanup so it is more obvious what the primary objective of the
heaven is.

It's only relevant for mouse events so only make it available there.

Don't ever leak the handlers, keep track of them and drop them when they
are no longer needed.

We currently have a `state` and a `states` module.  This is confusing,
rename the state module to `gamestate` to make a more obvious
distinction.

Copy the constants from www/src/_rc3-colors.scss to a rust module as
well.

Pretty graphics and it already exists so why not
