Fix vendored dependencies

[jsravn]

Remove 'vendor' from gitignore, and add stretchr dep that was previously added. Also remove glide install -v to catch broken vendor folder.

vendor got added to gitignore in a previous commit but the vendor folder was not removed, which was pretty confusing when trying to do dev. We could either remove vendor completely, or restore the prior behaviour which is what I've done here.

I think removing vendor and relying on glide install is better from the perspective of repo pollution. Dependencies are still going to have their revisions fixed in glide.lock but the repo won't be cluttered with all these unrelated files. What do you think?

[jsravn]

Removing vendor makes dev slightly more painful - need to remember to glide install on git pull. So I usually prefer having vendor. But I don't feel that strongly about it. It's more important we either fix vendor or remove it completely. If you'd like I can remove it.

[kobolog]

I think glide install is cleaner and I generally don't like clutter in the repo =)

@kobolog Okay, I made https://github.com/kobolog/gorb/pull/53 for it.
