React Refetch Versions Save

• Merge pull request #244 from Kiikurage/improve-type 313cadd
• Improve type definition to use optional chaining 959a03a

TypeScript improvements:

• Simple type definition fix to use promise factory method in "value" parameter https://github.com/heroku/react-refetch/pull/240
• Improved typing for PromiseState for better compile-time checks https://github.com/heroku/react-refetch/pull/241
• OuterProps & InnerProps declarations to separate props passed in from one injected by fetches https://github.com/heroku/react-refetch/pull/242

Breaking change for TypeScript users only

To support newer versions of React, this removes the use of deprecated React lifecycle hooks componentWillMount and componentWillReceiveProps, deprecated React Context API, and impure functions.

This is a breaking change from the 2.0 releases. To migrate, remove the use of the second context parameter and the pure option on any connect() functions. It generally should not impact applications, but be aware that fetches now happen on componentDidMount and componentDidUpdate.

This also updates many dependencies, which resolves security vulnerabilities.
