Experimental Facebook support

[28mm]

Facebook do image classification and captioning, which they expose via the <img alt=""> attribute, as well as face detection and recognition which are exposed via a user-tagging interface. Some of this may be exposed via a public api, the rest might require scraping logic.

Implementing a Facebook provider would involve

1. Using Facebook login credentials to build a private album
2. Uploading images to it
3. Retrieving detected faces and image labels via either a public api or a scraping tool like Selenium
