Improvements for large Libraries

• Preserves deep links (via #heading links) from Google Docs that are part of Library. 🙌, @maxine!
• Adds the ability to template the homepage modules by tag and description. Via @isaacwhite.
• Simplify running the app locally so that npm run watch always builds first. 🙌, @davegonzalez!
• Adds a warning when multiple documents or folders resolve to the same path in Library. 🙌, @jonpo!
• Adds a max height (400px) to folders on the View all Docs page, useful for larger Library sites. 🙌, @jdk27!

Also includes minor updates via npm audit fix and others.
