jsdom

[zackify]

Adding this means, there's no need for you to include jsdom in a setup file every time you write tests. This has a few hacks and things to make testing easier. I need feedback.

• monkey patch canUseDom due to the way react is loaded so that it is always true.
• expose React so that in tests you do not need to import React in order to use jsx syntax, ex : Test(<Component/>)
• jsdom is now a dependency of course.
• You must import this at the top of every test file for it work work correctly, or at least before you import middleware

I think that's all

fixes #3

Oh and moving to React .14 will be only a small pain I hope :D

Like it. I think it's now worth noting in the reader that node 4 or iojs is required.
