The only substantial difference here is that I made the harmony example use ES6
classes. The server rendering example was pretty wacky and hard to run but
I did confirm that it works.
I implemented this by checking for `type="text/jsx;harmony"`, since this
has a bit of a cleaner implementation rather than parsing a JSON object
out of a data attribute. If in the future there are other options to
pass, it would make sense to move to a system like that.
Along with adding support, there is also a new example added that's
the basic-jsx example with Harmony syntax.
