Mycouch show

Created a pull request to illustrate show. Added it as a separate context as it can be called with or without a docid. If approach looks okay, this can be replicated for .NET4 and PCL projects.

Please note: for custom query params, if one uses a sting as a value, the request adds an extra set of quotes, possibly due to use of Serialzer.ToJson. Same problem exists for lists. Is there a better way to send them?
