Links favicons via Fontawesome

[slayernominee]

it would be quite cool if there was an option to select an icon for a quick link not only via an url, but instead also from a list like font awesome (see nighttab extension for example).

oc there is a workaround by just simply puting the svg link from fa in the field, but it would make it way easier and give a better experience.

some sites dont have a favicon (sadly i know one ...) or an icon is not really expressive

may overlap in some areas with #460 and could possible be merged idk
