Title: Api tweaks wip

I'd like to be able to fetch updated/added records since a date. This way I can fetch records that have been created or changed since my last pull. Also, I think it's useful to know when a registration was created, and last updated, so I added those to the bike serializer as `registration_created_at` and `registration_updated_at`.
