Components as modules

Usual thing

[shamansir]

We can get rid of setup and state from Control by wrapping the state a.k.a. value with some type-marker rather than Property. That way Control is a pair of update : Event -> Value -> Value and view : Value -> Html msg, where Event has an option of Child Int Event so that we may update parents on child events. Then Control setup state msg becomes Control msg, bound to some Value, and we may store it in lists and nested structures!

Turned out not to be that usual, needs to be done together with separating Event. Partly done.
