Please add ZetScript about scriptorium

[jespa007]

Hi @r-lyeh-archived and happy new year,

I have recently updated ZetScript at 2.0.0. The speed it has increased ~2.5 times.

I attach the new release here,

zetscript-2.0.0.tar.gz

Howewer, with all the changes made, fib.zs script it has to change into the following,

function fibR(n)
{
    if (n < 2) { 
     	return n; 
    }

    return fibR(n-2)+fibR(n-1);
}

Console::outln("fib: {0}", fibR(34) );

By default cmake project it compiles ZetScript statically so I think it fits the requirements.

Cheers,
