Elliott Sprehn 5ef6774cd9 Add two way data binding.
All reflected attributes two way bind on SkyElement, so now doing
<sky-element name="sky-input" attributes="value:string"> is enough
to get two way binding on the value attribute so users doing
<sky-input value="{{ inputValue }}"> will get the inputValue property
updated as the user types.
