Consolidated NSValue categories to work around realm/jazzy#539. Documented MGLErrorCode. Moved jazzy configuration file into platform/ios/. Removed redundant include/Mapbox.h that was only being used by jazzy, now that the static frameworks’s umbrella header is based on that of the dynamic framework. Moved framework/Mapbox.h to include/Mapbox.h for consistency.
Include offline headers in the umbrella header used by the static framework. These includes are already present in the umbrella header used by the dynamic framework. jazzy relies on the static umbrella header to include all the headers, so the offline headers were also missing from documentation.
