Anthony Van de Gejuchte 06d9853a8b LibWeb: Update displayed favicon when a favicon is loaded
When a favicon has been loaded, trigger a favicon update on
document level. Of all the link tags in the header, the last
favicon that is load should be shown.

When the favicon could not be loaded, load the next icon in reverse tree
order.
