[main] adds ref: namespace

[titoBouzout]

Wanted to add ref as array, but noticed I could just add a ref: namespace and leave everything as is (from the perspective of the compiled code, it doesnt have to deal with arrays).

Currently, given how dom-expressions inline code the following just works (albeit is not obvious that it does):

<div ref={(el)=>el} ref={(el)=>el}/>

The problem is with Dynamic, this won't work:

<Dynamic component="div" ref={(el)=>el} ref={(el)=>el}/>

as compiles to:

  return _$createComponent(Dynamic, {
    component: "div",
    ref: el => el,
    ref: el => el
  });

But with the new namespace should work.

Notes:

• needs docs
• for whatever reason the refs are created in reverse order, I'm sure someone will notice at some point

Yeah this is worth considering. Definitely want to have a decision on this in 2.0. Could add this sooner though without a ton of impact I think.
