Webapi-Swagger : Add original name info into State/HashMap

[kahlil29]

Add the original name of a type/object as it appears in the Swagger (2.0) doc. This is done in order to preserve the original name for the instances that we have to generate. Also, this gives us the freedom to go ahead and use any naming strategy and rename the Haskell types as we see fit (in order to avoid naming conflicts).
