Spritely to SpritelyServerPlugin return Object simplification

[ca2longoria]

Summary

This currently returns as a Map<String,Object>, but that was originally intended for communication between SpritelyServerPlugin and Server. Since Server is simply passed along a full-on NanoHTTPD.Response, this oblique returning object was somehow scooted over to Spritely before I realized. Must eventually fix.

Concrete Requirements

• [ ] - Return object between Spritely and SpritelyServerPlugin is an object sensible for a pure Spritely application

Low priority, since everything does presently work, despite this odd mistake.

Referencing Issue #7.

Changing priority to medium, since I'll be implementing other REST API calls, soon, and they need to start off in the proper format.
