Title: Configure experiments from a hash

Make the helpers aware of an optional configuration hash. Simplifies
inline calls to `ab_test` and `finished`. As I mentioned earlier, this
is the first part of hopefully several additions I'd like to make to
experiment tracking.

I think this should fall back gracefully in all cases where the config file is
not provided.
