Extension is unusable until the page loads

[simonhearne]

On slower pages such as http://www.dailymail.co.uk/home/index.html it is quite likely that a user will click on the extension before the page completes loading. In this case there is no Start button and no indication why. The start button does not appear when the page does load, giving the impression that the extension is broken.

The issue is that the content script of the extension is added on document_idle to not interfere with the page. https://developer.chrome.com/extensions/content_scripts#run_at

@simonhearne is this an issue? please prioritize or close

Yes, we should at least have a 'please wait while the page loads...' message, then load the button asap.
