Provide iOS (iPad, iPod, iPhone) icons

[François Marier]

To provide a nice Libravatar logo for Apple devices (and possibly others?) accessing the site, we should add the favicon-like images described here:

Also see the StackOverflow discussion:

which mentions the "sizes" attribute for the favicon:
