Allow to use jsx

[wcastand]

add acorn-jsx as a dependency and allow nodent to handle jsx.

Fix #12

[developit]

Are you able to verify that this works locally?

[wcastand]

i tested it locally with yarn link on my test project and it built the project without error.
But i did not test my bundled packages in an app once it was built.

[developit]

awesome!

@developit has it been released? I couldn't make it work with jsx.
