Repo Name: Add .git

I noticed that if I do ...

```bash
git push http://localhost:7000/beep master
```

and
```bash
git push http://localhost:7000/beep.git master
```

It creates both beep and beep.git; so this appends .git to a repo name if it doesn't already have it.

Note that you can pull from both names, but only returns one.
