Include dotfiles in initial commit

[musoke]

I'm not sure if this is a feature request or a bug report.

I have a custom template that is a git repository containing a .gitignore. When I run pi init template directory, all the files other than .gitignore are staged. It would be nice if it was included.

The template is here in case this is an error on my part: https://github.com/musoke/tex-template/tree/1dc2c994b69d43517136f277b9be7f6b38f0c864
