Vendor Library: multi-json 1.0.3

Multi-JSON is a library that provides encode/decode support for casting Ruby
objects to JSON strings and back again. This version of the library has been
tested against ruby versions 1.8.6 and later.

Having a JSON encoder/decoder in the toolbox helps now that the GitHub API only
returns results in JSON format.
