UI tweaks for East Sussex

See https://github.com/mysociety/fixmystreet-commercial/issues/641 and https://github.com/mysociety/fixmystreet-commercial/issues/642

Have already had feedback on these, and addressed some concerns.

This overrides an entire template purely to change a CSS class of one span.
This is dangerous, as it loses any changes in the parent - you can see that this change was made before further changes to the fixmystreet template and it no longer matches up with the current behaviour thereby.
I would do this by adding a new more specific class to the span you wish to alter, which you can then target, this would not affect any other uses.
