Create querySelectorAll/matchesSelector selector option

[dmethvin]

As a lightweight option for a selector engine, provide a simple implementation that only uses the browser's native selector methods.

This would only be for 2.0 right now since IE6/7 absolutely needs Sizzle. Perhaps it could be added for 1.10 with the caveat that it only works back to IE8.

Any native qSA/mS bugs presently hidden by Sizzle will be re-exposed by this, which ain't our problem. There's a reason Sizzle is bigger.

Fix #13434: native-API selector module What's out:

• 6 KB
• attribute not equal selector
• positional selectors (:first; :eq(n); :odd; etc.)
• type selectors (:input; :checkbox; :button; etc.)
• state-based selectors (:animated; :visible; :hidden; etc.)
• :has(selector)
• custom selectors
• leading combinators (e.g., $collection.find("> *"))
• reliable functionality on XML fragments
• requiring all parts of a selector to match elements under context (e.g., $div.find("div > *") now matches children of $div)
• matching against non-elements
• reliable sorting of disconnected nodes Changeset: 1083f82d1ee0c8f15a66be15e6184294a69d4420
