citra_qt: Use the new verify backend; UI changes

Displayed username along with nickname (when they are not identical); Requested and displayed user's avatar; Made the dialog bigger for extended names.

Added a few functions to web_backend (GetImage, GetPlain) to support getting data in multiple content-types.

Added a no_avatar icon for users without avatars.
