Refactor NuGet packages
Change NuGet packages so they map 1:1 with ServiceStack projects. So 'Install-Package ServiceStack' doesn't bring in OrmLite and Redis automatically, and we can 'Install-Package ServiceStack.Interfaces' to bring in the minimum dependencies DTO's need.
The NuGet packages have been refactored in v4 which has the following deps:
ServiceStack.Common
– ServiceStack.Text
– ServiceStack.Interfaces
ServiceStack.Client
– ServiceStack.Text
– ServiceStack.Interfaces
ServiceStack
– ServiceStack.Common
– ServiceStack.Client
ServiceStack.Server
– ServiceStack
– ServiceStack.Redis
– ServiceStack.OrmLite
