"Report a problem here" button in nav when viewing a location

Fixes #2016.

When you load a page that includes either a problem report, or is
centered on a location, the "Report a problem" button in the nav bar
(that normally takes you to the homepage) becomes a "Report a(nother)
problem here" button, that leads directly to the new report form
for the location in question.

On full map pages (/around and any /report/<id> pages loaded via it)
the reporting form will be rendered client-side, avoiding a full page
reload.

On pages lacking the full map (eg: missing fixmystreet.bbox_strategy),
namely /reports/<area> and any /report/<id> page that hasn’t been
client-side loaded via /around, we fall back to a server-side page load.

Finally, as you’d expect, the text and URL for the button dynamically
update as you move around the map, or switch between the different
client-side states of the reporting flow.

We also hide the button entirely when you’re reporting a problem,
which was something suggested a long time ago.
