deps: upgrade npm to 2.8.4
This PR is branched from master
, not v1.x
, in keeping with @Fishrock123's feedback.
This is a fairly small release, and you can refer to the release notes for details. The most significant fix is the improvement in error-handling in node-tar
, although new users will also appreciate the tweaks that make npm init
more pleasant to use.
