BlockClosure as a JavaScript constructor

> Hi again :)
>
> As you know, a BlockClosure in Amber is a function in JS. It was already
> possible to use the 'new' operator in Amber with block closures, but
> without parameters only.
>
> Now Amber has BlockClosure>>newValue: and #newValue:value:
> #newValue:value:value:
>
> here's an example:
> new Foo();                // JS version
> Foo new.                  "Amber version"
>
> new Foo(1,2);             // JS version
> Foo newValue: 1 value: 2. "Amber version"
