Issue 6935 - Update HyperHTMLELement to render IOBigToggle too

To simplify IOElement lifecycle I've made some change to the HyperHTMLElement library that did not consider that IOSteps need to invoke created() N times and also inheritance might compromise initialization of each component.

Since, after investigation, I've discovered there was no issue with older Firefox, I've updated the library to render automatically on creation if no created method is available (already tested too).
