        Web Inspector: provide front-end wrappers for DOMAgent.querySelector[All]() that take care of fetching the document
        https://bugs.webkit.org/show_bug.cgi?id=57466

        - removed documentWide parameter to querySelector[All]() (user document node id instead)
        - factor out document request logic within DOMAgent into separate method
        - add querySelector() and querySelectorAll() to DOMAgent.js, assure we have document before calling back-end
        - use the above wrappers for querySelector() and querySelectorAll(), do not call backend directly
        - minor style fixes in Inspector.json
        - more error logging
