override gitconfig

[pfista]

For the personal .pp files I made for @sid9102 @bendbro, I just copied my .gitconfig, which means your global git name and email address will be mine. You should

1. Update your global defaults so it isn't my information
2. Version your dotfiles on github and update your respective .pp files to pull from that repo instead of mine.
