* npm: Upgrade to v3.8.3. Fixes a security flaw in the use of
authentication tokens in HTTP requests that would allow an attacker to
set up a server that could collect tokens from users of the command-line
interface. Authentication tokens have previously been sent with every
request made by the CLI for logged-in users, regardless of the destination
of the request. This update fixes this by only including those tokens
for requests made against the registry or registries used for the
current install. (Forrest L Norvell)
