homepage: Allow to add extra links on the home page
BLISS feature a default homepage.
There is more and more services provided around BLISS, like for example Daiquiri.
At BM05 it exists for example 3 Daiquiri addresses.
I think it would be nice to allow to add extra links in the home page.
I haven't yet checked. But extending a dedicated yaml file for that should not be a big deal.
