- Add compare mode and a description of the benchmark to the hosted version.

        * hosted/sunspider-results.html: Add compare mode - you can just paste in another results URL.
        * hosted/sunspider.html: Added intro text.
        * make-hosted: Copy new file.
        * resources/sunspider-compare-results.js: Made more reusable by putting the implementation in
        a function.
        * resources/sunspider-standalone-compare.js: Added. Calls the function in the way standalone mode
        expects.
        * sunspider-compare-results: Use sunspider-standalone-compare.js.
