updated FTE

[jgruen]

Updated the flow in FTE, see most recent attachment on the following bug: 

https://bugzilla.mozilla.org/show_bug.cgi?id=897600

Tweaks are minor and are (extremely) clearly noted. Expect Settings to follow soon.

Additionally, here’s a flat version of the provisional FxA logo that shouldn’t have any weird render issues:

I’m not adding this logo to the bug for fear it will accidentally become canonical :).
