Easy Config Mod for alternative JSX libraries like InfernoJS

[aaronclong]

Currently you must include /** @jsx Inferno */ at the beginning of every file with InfernoJs, a ReactJS like alternative.

It isn't very practical for developers because I already know that Inferno is being used simply by the imports alone. Most likely, future libraries will adopt the JSX model and standard shouldn't just assume React as the base.

A config in the package.json should be available to notify standard that an alternative library is being used.
