Title: Added git-upstream to easily add upstream repository

I thought that this shortcut might be useful to add to the list of extras. It is not very fancy, but it is something that I find myself doing every time I fork a repository.

Usage:
```bash
$ git upstream git://github.com/visionmedia/git-extras.git
```
