New issue 1253: offset text not in tex mode

Michael  Zingale:

The follow script (on some castro data):

```
import yt

ds = yt.load("smallplt16623")

s = yt.SlicePlot(ds, "z", "density")
s.save()
```

produces an image with the axes in 'km' and the offset text rendered as '1e4' instead of as $10^4$.

a related issue is that if you try to use `axes_unit='1e9*cm'`, you get a spurious `(1+z)` factor -- that is meaningless except possibly for cosmology codes, and should probably be suppressed by default.
