- Fix: Save broken on Firefox (since FF version?)

- Docs: Mention potentially more frequent release schedule
- Docs (ReleaseInstructions): Update per new testing; update
  `grep-doc` -> `types-doc` and indicate current failing status; indicate
  when `build-doc` will be used; clarify `npm pack`
- npm: Add newly renamed `jsdoc-check-overly-generic-types.js` to ignore
- npm: Bump to 3.1.1
