Add debug toolbar middleware.

If debug is enabled, using the CATALYST_DEBUG/FIXMYSTREET_APP_DEBUG
environment variables, add a debug toolbar to the output, including
request/response details and a database query log.

This uses Plack middleware, so works by switching our dev server to
use Starman with plack directly, rather than via the script runner.

We remove the GZip compression as this interferes, and take a local
copy of the QueryLog::AdoptPlack trait as it needs a tweak to work.
Make sure the CSP header is not output in debug mode, as that would
prevent the toolbar JavaScript from running.
