static/class properties

[Andrea Giammarchi]

I cannot remember if that has been considered historically a Java or PHP
error/ambiguity ... I'd rather not repeat that in ES6.

A Class constant should have nothing to do with instances but instances can
have properties that returns that class constant, if needed.

We've got new syntax here so I say this is the easier to
read/write/understand ... no need a big chapter explaining what's going on
^_^

```javascript
class A {
  static A.VALUE = 10;
}
```

or ...

```javascript
class A {
  static {
    VALUE = 10;
  }
}
```

as in [redefine.js](https://github.com/WebReflection/redefine#classes)


Both will desugar in

```javascript
function A(){}
Object.defineProperty(A, 'VALUE', {value: 10});
```

leaving the prototype alone with its own different world problems.

My 2 cents
