Proposal: Return UJS as a public API

[robrobbins]

Doing a SPA with react I have found it beneficial to have unmountReactComponents publicly accessible. I have modded the react_ujs file in this project to do this easily enough. I think there is an interesting discussion that can take place around this:

1. making it a 'revealing module pattern' is simple but where should it live really? A ReactUjs obj ? I actually just append it to React itself as React.ujs accessing them, obviously, as React.ujs.unmountComponent etc...

2. I realize this may be outside of the scope you want to address with the gem. That being the case I can fork and maintain it separately

3. If interested I can work up a PR with the appropriate tests

I'm in favor (after stewing on it a bit), one approach was tried here also: #91

I see. My use case is a bit different: In an app using a router (Backbone.Router for example) you will have instances where your pushState URL is rendered via the server (a cold refresh) but then is handed to the client. When navigating away I want the components (as well as the then empty data-react-class wrappers) removed from the DOM as my router will call for those after.

I will, for this PR actually create a separate react_ujs (react_ujs_api or some shit) file so that we can open this conv up a little more with some code to look at. I'll get to it tonight
