Dexie Cloud

You can use your when creating databases using npx dexie-cloud create. Let me know if you need more email addresses added!

Some new docs were added [Dexie Cloud docs](https://dexie.org/cloud/docs/) in recent days. Unless you already have the grip of it, one way to get started with the service is by playing around with the [todo-list sample app](https://github.com/dexie/Dexie.js/tree/master/samples/dexie-cloud-todo-app).

Seems like it should be possible to create 2 classes of files:

1. URL Accessible File - Default file type, public (anyone with the link can edit), editable and shareable. Referenced by a UUID. Also contains a File Name.
2. Readonly Demo - These create a copy of a demo file as a URL Accessible File.
