Accessibility issues with Add/Edit/Login/Delete links

[KiloTango]

Issue description

In numerous places across the tutorial it just uses icon fonts on the edit/new/delete etc links, with no actual text. This is fairly bad accessibility practice (as screen readers won't be able to pick it up) and we might as well give people good habits from the start, especially as including the text would make the code of those links even more clear as well.

Using a <header> for the top part instead of a <div> would also be more semantic and accessible while also being nice and human-readable as well.
