Decided on a domain and added TypeScript

I finally decided on a domain for my GSuite-Wiki: https://www.fulcrum.wiki.

During the last sprint began using TypeScript for Fulcrum. This will be of course an ongoing process. I us the approach to write the type annotations with JSDoc as long as I don't reach critical mass and will then switch to full TypeScript.

During the last sprint I added several features to Fulcrum:

1. You can share your work with others to view and collaborate.
2. You can now easily see what you read and edited last, and continue at any time.
3. You can access all your files on your Google Drive from Fulcrum and vice versa.
