v1.2.0

Added

• Add :returning option to use Drill
• Allow user to set :source to table name instead of schema
• Add :repo to Drill.Context
• Allow user to override location of seeder file through seeds_path option when running mix drill. E.g. mix drill -r MyApp.Repo --seeds-path priv/seeds/core
• Allow manual seeds and set callback factory/0 to optional

Fixed

• Remove running migration when running task. Migration should now be run explicitly before running mix drill
• Start all registered apps before seeding to ensure apps required by seeds have started such as uploaders, genservers, dependencies, etc.
