Merge lp:~cjwatson/launchpad/pil-image into lp:launchpad

[Colin Watson]

Use "from PIL import Image" rather than "import Image".

The latter is deprecated, and no longer works in bionic.

We should probably move this into the virtualenv at some point rather than relying on a system dependency, but that'll require new -dev dependencies and is generally a bit more complicated than just chasing the module renaming.
