deps: upgrade to npm 2.14.12
Hiii!
This PR includes two releases:
The main thing to note is a hopefully welcome update to our licensing to clarify scope of both the open source side and the registry TOS. There's a further clarification coming later this week, so we're not done with that bit yet -- so keep an eye out for v2.14.13.
This PR supersedes #4003, but have a look-see over there for some discussion. That PR should be closeable, though. #4033 was closed because I made it against the wrong branch. Sorry about that. :)
