Moved RiakIndex to its own file
Commented out most of the WIP index stuff while I refactor the Converter/Serializer stuf

The whole RiakIndex thing forced me to have another look at how values were (de)serialized since somehow serialization also had to provide a set of indexes and that didn't work very well with the current design. That is now in progress
Commenting out the SprayJsonConverter stuff while I refactor the whole converter system
Cleaned up unused imports
Refactored the Converter system into a simpler Serializer/Deserializer system that just focusses on the transformation of T => (String, ContentType) and back again.

Unit tests for the basic serialization support classes are WIP while I go and get some sleep
