TPAC: Display authors using inline-block

Rather than letting author credits wrap willy-nilly, use inline-block mode so
that each line will begin with a new author. Devices with constrained screens
in particular benefit from this, as the list of authors is much easier to scan,
and wider screens can still fit multiple authors on a single line.
