Add .gitignore to aiken new project generation

[MitchTurner]

What is your idea? Provide a use case.

When you run aiken new the project comes with a free .gitignore:

build
assets

aiken.lock

Why is it a good idea?

Most people don't need to include all their dependencies in the /build directory in their repo. /assets and aiken.lock are also often superfluous.

What is the current alternative and why is it not good enough?

You could add it by hand.
But I think most people are gonna want /build and /assets and aiken.lock ignored from their repo.

the aiken.lock file should not be ignored

@rvcas
Cool. I'm curious why you'd want to keep it. I've seen people go both ways with cargo.lock and I've never given it the time to understand why.

@MitchTurner I believe it's related to reproducible builds or something, I've always committed the lock file for everything so I was under the impression it was a settled matter.
