Support Functional Stateless Components

[theKashey]

Currently it just removes prop-types at all, and converts SFC into a simple function.

Something I love to work on. I would gladly help you implement it if you want to get your hands dirty with TypeScript compiler APIs as well.

As long I really need it - might be I should be a right one to implement it.
Let me dive deeper into the current code to roughly get idea how it works, and then I'll ask you to help.

I have recently refactor my project to use TypeScript and I've do some work to improve the code base and add more transforms. including:

• Update TypeScript to 2.6 Update TypeScript to 2.6 #16
• Stateless Components Support stateless component #23
• Support more PropTypes: Support more prop types #19
  • PropTypes.oneOf() // limited, only support string or number literal array oneOf(['a', 'b', 'c'])
  • PropTypes.oneOfType()
  • PropTypes.arrayOf()
  • // Maybe more
• Remove import PropTypes from 'prop-types'
• React import: import React, { Component } from 'react' => import * as React from 'react' // Can be dangerous, need more discussion.

I'd like to polish it up and send some pull requests to review & discuss.
