Added type field to Zone.Get.Initial.Entity.Positions
Added method Zone.Move.Entity, currently in test mode
Made modifications to explode function in web_interface_utils.h
Added web_interface_utils.cpp/.h to common to provide string based functions for outputting JSON
Adjusted CMake to include rapidjson library and new web_interface_utils.h/cpp to common
Currently, I have code set up hackishly for testing so do not think it is final. It is merely for demonstrating what I've done and played with.
