[openstreetmap-website] Gravatar support (#131)

[Paweł Paprota]

This adds support for the popular (e.g. used here on Github) Gravatar service to osm.org.

I added a simple checkbox on the account page instead of trying to hook into the whole user image new/replace/delete magic. Hope this is OK UI-wise.

One thing I still need to look into is the image size - i.e. how to get image size from Paperclip styles based on style name. Other than that it's up for review.
