Use single quotes for strings generated by JSX

Kind of hacky, but very simple and robust if this is something we want to commit to.

Could easily make it configurable (certainly preferable), but I'm not familiar with the code/modules that makes up the JSX runnable and there doesn't seem to be an intuitive way of accessing options in the visitors themselves.

Yea, would definitely need to make this configurable before we could take it.

I know @andreypopp has a fork of eslint that works with JSX; if it can be packaged up maybe it's worth just suggesting people use that so we don't need to worry about the quoting debate:

I think it would be nice to have this feature though. There are lots of other tools (jshint, jscs,..) and I'm not sure that forking all of these is the way to go. It would be nice if the output of the generated JSX could pass linting.

We aren't going to merge this in its current form at least, so I'm closing this out for now.
