[strctr]

Add ability to define flow config inside package.json.

IMHO, this is important to follow best JS development practices, even if tool written in other language than JS. The other request is to replace OCaml regex with regular JS regex to avoid confusion when have to configure .flowconfig.

For reference/easier findability, these are the flowconfig related issues/suggestions I found that would bring it in line with other tools like eslint, babel, webpack, etc:

• https://github.com/facebook/flow/issues/4115 : What about .flowconfig.js
  https://github.com/facebook/flow/issues/153 : .flowconfig should use json
• https://github.com/facebook/flow/issues/238 : .flowconfig should recursively consider other .flowconfig files
