Switch to generated client for www => api
Update default handling for fields and parameters

 - Main change is to remove Option[x] for parameters/fields
   that are optional but have defaults
 - Changes API from Option[Limit] = None to Limit: Int = 25
remove debug
Keep defaults only server side
List => Seq, put back qualified scala package for Option to avoid conflict
Merge pull request #17 from gilt/client
