Bugfixes

- Brought Jeffrey Tierney's Blob update back.  IT'S BETTER THAN EVER!
- When the Blob isn't supported, the JSON data will be written to a <textarea> and automatically selected so it can be copied and pasted into an editor.
- I was replacing the entire document with each page iteration when I should've just been replacing the contents of <body>. Fixed this and now no longer get the intermittent error that was occurring via Netflix's own script.
