Summary: Documents can now be flagged as tutorials, which causes them to display Markdown-formatted slides from a special GristDocTutorial table. Tutorial documents are forked on open, and remember the last slide a user was on. They can be restarted too, which prepares a new fork of the tutorial. Test Plan: Browser tests.
