Added support for React 16

[DPr00f]

@ctrlplusb I've been using react-jobs with react-universally and react@16
There's nothing within react-jobs that would prevent it from working with react@16
Can you please do a minor release?

Hey @DPr00f. Apologies for not getting to this yet. Was there a specific reason you decided to close this?

[DPr00f]

No worries @ctrlplusb ,
The reason is that those changes are in the #43 already.
Feel free to reopen it if you want to do this one before #43 or if you don't want to merge #43 at all
