Chris Finch's styling for the profile upload, but nothing more
Add support for uploading Avatars [#IDN-1774]

Allows users to upload new Avatars for their profile:

https://profile.thegulocal.com/public/edit

The avatars are sent for moderation in the Discussion tool, so they're not
available immediately.

The Avatar upload system we're hooking into /could/ be described as
legacy. The fact that it uses GAE is not the problem, the dependency on
the Guardian DocRoot (rather than S3) is closer to the mark.
