Douglas Creager cf803555e5 Make error reporter API generic
Instead of hard-coding the HTTP API we use for uploading errors to our
internal service, let the user provide an arbitrary function (in the IO
monad) for uploading them.  The default config will create an error
reporter that logs errors to the console, just like happened before if
you didn't set the `HAYSTACK_URL` environment variable.
