Updating .gitignore

Ignoring Pants's byproduct files.

If you use Git, we recommend adding these lines to your top-level .gitignore file:

# Pants workspace files


FYI: your .gitignore is used to auto-populate the option pants_ignore

Occasionally, you will want to ignore something with Git, but still want Pants to work on the file. See Troubleshooting / common issues for how to do this.
