Merge tag '0.1.0' into dev

v0.1.0 release
 * no longer throws `RangeError` when element is not found
 * more elements can be used as the `root` (although `<form>` and `<fieldset>` are preferred)
 * returns `Array` instead of `NodeList` where relevant
adding a brute-force search for IE as a fallback

when you want to find a `<fieldset>`, even if it has a `name` attribute, IE won't
return it when using `namedItem()`, so if nothing is found on the first pass, it will
fall back to the brute-force `querySelectorAll()` search just in case.
