Update migration, fix various minor issues

- Lot of people couldn't migrate to v1 and plan to reevaluate when v2 is
  released.
- It's "npm" not "NPM". It doesn't stand for anything, and it never
  has - it was initially chosen simply because it was easy to type.
  It has a lot of unofficial backronyms with "Node Package Manager"
  being one of the most common ones, but it's never officially stood
  for anything as an acronym *or* initialism.
- Fixed a few errors in the change log, like non-breaking changes being
  included in the "Breaking Changes" section and an inaccuracy in the
  summary of a particular change.
- Fixed RawGit URLs to point to GitHack, which is a lighter proxy that
  offloads caching to Cloudflare instead of also implementing it itself.
  (It also just uses nginx for all the important server logic, so it
  scales better.)
- Add a few more v0.2 references as appropriate
