Remove Gemfury; we don't need it here any more.
Remove old Statsd event counting.

This wasn't giving us useful metrics -- at least, it wasn't giving us
metrics we were using. Infrequent events like edition state changes
aren't ideally suited to the Statsd flush interval of 5 seconds.

Also, we've now settled on a namespace of `govuk.app.<appname>`, which
this predates.
Add a class to report state counts to Statsd.
Set up Statsd client directly in an initialiser.
Report edition state counts to Statsd.

These get reported in a filter, after any accounts that try to change
edition states. These reports fire even if the action fails, but since
they're just updating gauges, this shouldn't be a problem.
