Report more about what init is doing

From @peterbourgon in #131 (comment):

I think we need to have init print out what it's doing, even at a coarse level ("cloning foo/bar/baz") and even without -v.

It'd be great to have someone go through and weave in some of this additional output. If anyone's interested, please feel free to ask questions here, or over in the gopher slack!

Id like to help out with this one. Just cloned the repo so grocking the code now.

Ok. I get the flow of init. I quickly wrote some basic logic to range through all the Manifest dependencies after a successful call to sw.WriteAllSafe and print out Cloning: github.com/hulk-hogan/legdrop for each.

Cloning: github.com/emicklei/go-restful
Cloning: github.com/go-kit/kit
Cloning: gopkg.in/mgutz/dat.v1
Cloning: github.com/stretchr/testify

Currently this is happening regardless of wether the -v flag is passed or not.

Not sure if this is exactly what is being looked for with this issue. Id love some feedback so I can continue to move forward with this.

@xmattstrongx from that description, it sounds like it's not quite what we're looking for with this - it'll probably be printing after all the time-consuming work is already done. But put up what you have as a PR, and we can take a more in-depth look.

I think we can call this closed now; can make a new one if specific new changes are needed.
