Fixing Google Analytics that seem broken for all pages except blog pages

	- re-added code to default.html
	- removed code from app.js
I think we should keep this in here as well since there are some non-GA tags in the Tealium admin, I believe. If you are concerned about double-counting in GA (through Tealium and through the code below), I'd remove the GA tag from the Tealium admin for now.
