Use git repository as project starter template

[egillespie]

Several projects have requirements that ask students to start with a specific set of files (e.g. HTML, CSS, etc.). It would be helpful if a project could be assigned the URL of a git repository so that when a student clicks "Start Project", their git repository is automatically seeded from or created as a fork of the project starter repository.

This feature opens up other exciting possibilities as well:

• Automation with GitHub Actions
• Provided unit tests
• Project-specific VS Code settings
• Built-in .gitignore
• Requirements incorporated into README

This feature should be used with caution though:

• A big project may be intimidating or distracting to new developers
• How to handle changes to automation (unit tests, editor config, ignore files, etc.)
• How to handle a project template changing (should a specific commit be used as well?)
