Fix legbility of output, simplify code

Some simplification has taken place, and effort has been made to unify
the output.

getur.pl
    - Now using Smart::Comments over Term::ProgressBar. It looks better,
      is easier to implement and saves us a little headroom.
    - Output now has a consistent theme, making things more legible.
