Support for internal controllers

[Melchy]

Internal constructors are currently not supported. Ridge fails with "action not found error".

Internal controllers and internal actions can also use internal objects. If internal constructor or internal action uses internal object then ridge generates client with public methods in public class that use internal object. This causes build to fail.

Proposed solution

• Ridge must be able to generate client for internal class.
• When controller is internal ridge should generate internal client.
• When action is internal ridge should generate internal client method.
