User plugin integration with lightdm

[RichJack]

Lightdm is the display manager used by Ubuntu and many other distributions.

If the downloaded Gravatar (or G+) profile pic is downloaded to ~/.face then it will also be displayed by the login manager.

Also it would be useful if the tooltip could be customized to display eg $USER is logged in.
