Add json support to wpiutil.
This is a modified version of https://github.com/nlohmann/json. It's been moved into the wpi namespace as many of the changes are not compatible. The amount of template code has been significantly reduced, enabling many functions to be moved out-of-line, and for the result to build on older compiler versions (in particular GCC 4.8).
