Initialize git repository on project spin up

[dcalhoun]

• Initialize a git repository for the project
• Use git repository info to pre-populate GitHub Pages config

@dcalhoun ❤️ this. Should be fairly easy with shelljs (e.g. shelljs.exec('git init')). Are we assuming that the name of the project will be the name of the repo? I guess it's possible you could name the project and repo something different...

We could make assumptions and provide the user the ability to alter them, much like we already do with the "What is your name?" and "What is your email?" prompts. The appName is currently generated from the directory name.

Should we also optionally hit the GitHub API and create the remote for you as well like we do in preseason?

If someone decides to dig into this, please assign yourself to the issue so we're not double-dipping the initial work. I may take a crack at it this weekend if it's still unassigned.
