Upgrade vulnerable MarkBind dependencies (#788)

Upgrade vulnerable dependencies reported by npm audit:

    Live preview:
        * chokidar: 1.6.1 -> 2.1.5
        * live-server: 1.2.0 -> 1.2.1
    GitHub Pages deployment:
        * gh-pages: 1.1.0 -> 2.0.1
    Building pages:
        * fastmatter: 2.0.1 -> 2.1.0
        * nunjucks: 3.0.0 -> 3.2.0
        * markdown-it-table-of-contents: 0.3.2 -> 0.4.3
    Development tools:
        * eslint: 4.16.0 -> 5.15.3
        * jest: 22.4.3 -> 24.5.0
        * lodash: 4.17.5 -> 4.17.11

During the upgrade of eslint, there are rule specifications that has
changed or deprecated, so some configuration also needs to be updated.
Required upgrades to eslint configs:

    * eslint-config-airbnb-base: 12.1.0 -> 13.1.0
    * eslint-plugin-import: 2.8.0 -> 2.16.0a
    * eslint-plugin-lodash: 2.6.1 -> 5.1.0

Let's also disable new ESLint rules, `no-else-return` and
`implicit-arrow-linebreak`, to comply with existing styles, and
fix import order to match ESLint new sort-import rule.
