The "Next" button on the annotation page should send me to the next category, not the download page

[surchs]

When I click "Next" during the Annotation workflow, I should jump to the next unannotated category so that I can continue annotating. If all categories have already been annotated, then the "Next" button can transport me to the next page (e.g. the Download page).

The main goal here is to make it easier to navigate through the Annotation workflow. At the moment, the annotation workflow involves scrolling (and annotating) from top to bottom. So when you're done, you are probably near the bottom of the page and can't see the list of categories anymore (but see #239). Because the "Next" button is near the bottom of the page, it would be a natural UI element to allow the user to continue the process.

Makes sense as it doesn't break the tool's 'next' paradigm so much as it slightly alters is it for this multi-step page.

This would involved page jump (up) functionality, something we have yet to attempt.

+1 for this issue - my intuition is still to click "Next" when I use the annotation tool.
