TODO: Besides splitting this out from previous commit, should really avoid markdown field in favor of modifying jsdoc to report wherever it lays out "prettyprint"; still probably missing some one-liners; see https://github.com/google/code-prettify; update builds to confirm new stackblur is working; add below to CHANGES; add back for eslint-plugin-jsdoc once merged (though need new version ^3.9.1); move any linting changes to other linting branch

- Refactoring (minor): Add favicon to canvas demo
- Linting (ESLint Markdown JavaScript): Add `eslint-plugin-markdown` with
  slightly loosened config (`no-undef` and `padded-blocks` off and
  `no-unused-vars` as a warning)
- Linting (ESLint JSDoc code comments): Add `eslint-plugin-jsdoc` and apply to
    JSDoc code comments
- Linting (ESLint): Completely avoid unescaped tabs in files
- Docs (Linting): Add linting info file
- npm: Rename `copy-deps` script to `copy`
- Refactoring: Add stackblur-canvas as a dependency and copy it in (until such time as we can do so for canvg)
