remove unnecessary list bullets in footer

The footer currently has the bullets from both the default list-style-type,
as well as the :before conditional. The :before conditional is meant to
generate bullets between entries, while the list-style-type generates them
before each entry. As such, i believe disabling the list-style-type will
create the desired visuals.
shorter, and afaik, still valid
