Note we're keeping this section's original design (which had one button
to add a new group which after being pressed was replaced by a button to
cancel) but we aren't using Foundation's `data-toggle` because there
were a couple of usability and accessibility issues.
First, using `data-toggle` multiple times and applying it to multiple
elements led to the "cancel" button not being available after submitting
a form with errors. Fixing it made the code more complicated.
Second, the "Add new group" button always had the `aria-expanded`
attribute set to "true", so my screen reader was announcing the button
as expanded even when it wasn't. I didn't manage to fix it using
`data-toggle`.
Finally, after pressing either the "Add new group" and "Cancel" buttons,
the keyboard focus was lost since the elements disappeared.
So we're simplifying the HTML and adding some custom JavaScript to be
able to handle the focus and manually setting the `aria-expanded`
attribute.

Note the CSS could probably be improved to avoid duplication with other
button style definitions. However, that's fine because we're going to
change the style of the links soon.
For the same reason, I haven't bothered to style every single link the
way it was until now.
This partial was going to get too complex since in some places we've got
different texts, different URLs or different confirmation messages.
While we should probably try to be more consistent and that would make
the partial work in most cases, there'll always be some exceptions, and
using a partial (with, perhaps, some helper methods) will become messy
really quickly.
