Moved the old benchmarking application.conf settings to the test/resources/application.conf because reference.conf should only contains library-specific default settings
Changed the type of the value contained within a RiakValue to String since that what it mostly is and that what you mostly want it to be (to begin with).

Byte array conversion is now done in the conversion to/from HttpRequest/HttpResponse
Added some initial steps to write back the value after a conflict has been resolved but ran into a design issue that I'll discuss with the feedback group tomorrow
