### Pimp the docs linter (and assorted changes)
#### `scripts/lint-docs.js`
- Add an optional cache for faster runs
- Add a final report
- Don't return anything from `exec()`
- Cover more files
#### `scripts/_command.js`
- Look for a "--cache" option
#### `package.json` scripts
- Added `watch:lint-docs`
- Added `cleanup:lint` to remove the eslint and lint-docs cache files
- Changed `lint:docs` to use the `--cache` option
- Added `test:js` so that we can run the test suite without the linter
- Changed `test` to defer to `test:js`
#### Actual lint fixes:
- Bad link in a migration guide
- The unicode dashes in the "https://en.wikipedia.org/wiki/Subject–verb–object" are not escaped by marked
### Some more lint-docs pimping
#### `scripts/lint-docs.js`
- some code reorg and cleanup (take a hint from the local coding conventions)
- fix misc bugs
- pass a User-Agent header to the requests
- even nicer reporting
#### `package.json`
- bump the @babel/parser dep to the latest
#### Docs
- tweaks based on lints missed due to previous bugs
### Docs: use the github page for velocity.js, the home page has too many errors.

- Correct docs generation to always fetch its dependency
- Don't try to close a handle that's already been closed by other methods
- Allow the release script to actually be testable.
