Add links over figure numbers

[bsipocz]

We have 2, and in some cases 3 versions for the figures. The book editions are available from the drop downs, but it would be best to have way to navigate between the versions on the figure level, too.

E.g. turn the figure number, at top of each page, to a menu of 3 links that points to the different versions gone into the print.

Brilliant, this is kind of a duplicate of #9, I should have checked the open issue first.
