Improve visibility of page state

[dainnilsson]

Background Several of the "tabs" in the tool have sub-pages. For example, the "Static Password" tab has "Scan Code" and "Advanced" buttons, which open up new pages. The issue here is that once you've clicked on "Scan Code" it's not very easy to tell that you've entered a sub-page. Switching to another tab and then back puts you right back into the "Scan Code" page, making it very easy to forget that there was an "Advanced" page as well.

The only way to see that there is indeed a level above "Scan Code" is the "Back" button located in the lower right part of the page (not always the same position, this depends on which page you're viewing).

Suggestion Move the "Back" button to a more visible place and indicate clearly that there is a level above the current one. This can be done by sticking it near the top pf the page, in a bar of its own, for example (excuse the ASCII art):

... OATH-HOTP   Static Password   Challenge-Response ...
