This way we'll be able to apply it to the SDG icon, which is not
included in font-awesome.
Note we're adding a font-icon selector so it's defined before the
admin-menu-icon selector and so in case of conflicting rules the ones in
the admin-menu-icon selector are used.
This way we simplify the HTML and generating similar menus will be
easier. We also improve the experience for screen reader users, who
might have been hearing the icons as text because we weren't using the
`aria-hidden` attribute.
We're still keeping the "icon-" classes for compatibility with CONSUL
installations which might have changed this code.
From a semantic point of view, there's no reason to add a strong
emphasis to the menu items.
Besides, using CSS simplifies the code and is less error-prone. For
instance, the "stats" section didn't have a <strong> tag, and so it was
the only one which wasn't bold.
The planned budget investments redesign includes using icons in some
tables, so we might as well use them everywhere.
The original design used Foundation to show the tooltips. We're using
CSS in order to keep the ERB/HTML code simple. One advantage of using
CSS is we can show the tooltip on focus as well, just like accessibility
guidelines recommend [1]. On the other hand, Foundation tooltips appear
on the sides when the link is at the bottom of the page, making sure
they're visible in this case, while CSS tooltips do not. Neither CSS
tooltips nor Foundation tooltips are dismissable, which might be an
accessibility issue.
Note we aren't changing any ERB files in order to replace links with
icons; we're only changing CSS and one line of Ruby code.

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.
In the past we were using some <div> tags surrounding table action
links in order to guarantee these links wouldn't be wider that their
cell's space and wouldn't expand over two lines.
However, while these links didn't expand over two lines, at certain
resolutions the width of their text exceeded the width of the links,
causing part of the text to be outside their borders.
This behavior was also inconsistent: some tables had these <div> tags,
and some tables didn't.
Since we've now introduced the table actions component, the code is more
consistent and we're getting rid of these <div> tags. So now we're again
facing the issue where links could expand over two lines.
Using a flex layout solves this issue and considerably improves the
layout at lower resolutions.
