Component fix

The component package of noflo-adapters is a bit broken at the moment.
It's missing a couple of dependencies : underscore and owl-deepcopy.
owl-deepcopy not having a component package right now, I created it on my account and also sent a pull request (if accepted I'll change the dep later).

There is also the issue of .fbp files not included in the browser version of noflo-adapters. Not sure whether I'm missing something here or if it's an actually issue...
