support foo["bar"] in addition to foo.bar

Browse source 
* module/language/ecmascript/parse.scm (parse-ecmascript): And update the
  function declaration forms for the new var syntax.

* module/language/ecmascript/compile-ghil.scm (comp): Support foo["bar"]
  in addition to foo.bar.

* module/language/ecmascript/impl.scm (pget, pput): Some fixes for when
  we get non-symbols -- it can happen, yo. I suppose we should allow for
  non-string keys too..
