ReactLink for radio buttons (radioLink)

[guybenron]

Adresses #3573 .

I modified LinkedValueUtils.js to add support for the following syntax:

<input type="radio" name="mygroup" value="value1" radioLink={this.linkState("myval")}/>
<input type="radio" name="mygroup" value="value2" radioLink={this.linkState("myval")}/>

State will have a variable named myval that will hold the radio buttons value attribute (e.g., value1 or value2). Setting this state variable to a specific value will cause the corresponding radio button to be selected. If there is no corresponding radio button, all will be deselected.

Also updated documentation.

So ummmm... what's the next step?

I'm already using this patch, so I hope it will be merged soon

@guybenron maybe they are waiting for you to solve the merge conflicts

#2302, ReactLink is probably going to be deprecated so possibly never, but that's not my call. You can easily provide your own enhanced input-component wrapper which provides this behavior rather than having it be supported by React core, that's my recommendation.

PS. It really should be called checkedLink (the property is called checked), not radioLink.

Yea, sorry. ReactLink is getting deprecated. I recommend that you implement a wrapper component and publish it to npm.
