Add .gitignore to scaffolding process

[CodeSpent]

I'm not sure if this is an oversight, or intentional, but I'd love to have the discussion documented. There is currently no .gitignore boilerplate, which adds a little extra work after starting the project. I'm proposing adding this, and potentially also adding the git init step to the scaffolding process.

I think it is fair to assume (or just provide an option) that someone would be using git for these projects, so could be a tiny win to go from running the create apollo-app command to writing code straight away.

I'm happy to contribute this if maintainers approve of this idea?

@CodeSpent I'm fine with this idea, but we should ignore git init errors, so that if use do not have git installed it won't fail

[CodeSpent]

@larixer great, I can handle that. Do you think it'd make more sense to add a second option after the initial menu selection asking the user if they want to initialize git? Can still fail silently, but this would also let them opt out of a .gitignore if for any reason they don't want one.

@CodeSpent I think pretty much everyone uses git these days, so just failing with a warning is fine, IMO, no need to complicate the task for yourself
