html to jsx as a separate tool

[jhiswin]

Instead of having html-jsx-lib.js buried inside the docs folder, it could be extracted as a separate tool. HTMLtoJSX can be used with jsdom as a separate tool, and bundled in a package like react-tools.

This is a great idea. I'd love for us to have a more complete set of tooling available.

This was done when I split html-jsx-lib out into the React-Magic project. You can get the tool from NPM at https://www.npmjs.org/package/htmltojsx (although I haven't done as much testing with the Node.js version compared to the web-based version).
