First stab at insertCSS example; very rough; form for modifying css not hooked up; layout horribly incomplete
Removing asset no longer needed
Fixed layout to be more uniform and straightforward
- Pass input form and elements to Css object
- Load initial css file via xhr
- On form commit: update URL regular expression and CSS from form, then
  reload
- Disable inputs until values are loaded
- Inline CSS background image to avoid mixing HTTP/HTTPS upon injection
- Save regular expression and CSS to local storage
Make injected CSS rules important!
Fix missing re-layout on vertical resize (mostly, anyway) with position: relative
Make form stand out a bit more
Adding README and assets to insert-css webview example
Remove superfluous logging
