Works for me.  The error message should be informative enough in the other cases.

Scalar coordinates- this is the current behavior:

```
In [16]: a = xray.DataArray(np.random.randn(3, 4))

In [17]: a.coords['foo'] = 123

In [18]: a.plot()
```

So scalar coordinates do show up in the title, which is what I was going for. I could add a test for this.

> labelling facets will be more reliable if it is done explicitly in the same code that is doing the indexing/groupby.

That's the approach that I've moved to after spending more time on it. This PR adds the argument `add_labels` to 2d plotting functions. Now for the faceting I'll actually use `add_labels=False`.
