Champions League Dataset typos

• Aberdeen is mentioned as Abderdeen in some lines, and the country is NA instead of SCO:
  champs[is.na(champs$hcountry) | is.na(champs$vcountry),
  c("home","hcountry", "visitor", "vcountry")]

• ASK Vorwarts Berlin is mentioned also as Vorwarts Berlin from mid '66 season onwards:
  champs[champs$home == 'Vorwarts Berlin' | champs$visitor == 'Vorwarts Berlin' |
  champs$home == 'ASK Vorwarts Berlin' | champs$visitor == 'ASK Vorwarts Berlin',
  c("Season", "home", "visitor")]
