Title: Add Commit.subject

Allow easy retrieval of a commit's subject.

This would look better if we could mix python and C in the bindings, as it would become something like (ignoring the actual syntax)

```
commit.subject => commit.message[0:commit.message.find("\n\n")]
```

which works IIRC the code I've on the other computer. No idea if that's possible.
