Make Google Docs work better

We implemented some workarounds to make Read Aloud work more smoothly with Google Docs. This requires some new permissions to be granted for the docs.google.com website. These permissions allow Read Aloud to inject a few lines of code when the docs.google.com page is loaded, and configure Docs to render the document in HTML instead of as a canvas. All the injected code are included in the extension package, no remote code is loaded or executed. And no information is collected or sent to the Read Aloud servers.
