* Choosers: refactor to use SVG icons
Refactored non-deprecated choosers to use SVG icons. Custom choosers can
also supply their own svg icons using the `chosen_icon` and
`unchosen_icon` blocks.
We are keeping the relevant icon font css for custom choosers around to
prevent breaking existing custom choosers.
