seeder

Seed TMS tiles and store them on Amazon S3 under a specific tile version. Tiles can later be fetched via a tile-broker.

The seeder will push jobs on a priority job queue backed by the redis instance at REDIS_URL. Jobs are pulled from the queue by tile-workers who will render the tiles and store them on Amazon S3 under the correct tile version.
