This is a WIP PR.

@ilanbiala have you looked into PM2 to replace Forever?

@simison I don't really see any major benefits over forever.

@simison Unitech doesn't credit their contributors anymore, so I prefer not to support a project that doesn't give credit to the authors.

[lirantal]

we're using PM2 at work as well.

[ilanbiala]

@lirantal Node 0.12 only has failing tests. However, I'd prefer to wait for us to up the test coverage before finalizing this because then we'll have to do less testing before merging.

[lirantal]

Cool, fine by me.

[ilanbiala]

Not a great idea to do this at once, so I'm closing and we'll do it incrementally as much as we can.
