Add harmony transform support in browser (Fixes GH-1420)

Browse Source 
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.
