Wolfgang Stöggl 66b533c284 Bump copyright year to 2020 
The copyright year was last time updated in 2018. There is some cleanup
involved in this commit and the next copyright year update is supposed
to be simpler (i.e. substitute "-2020").

- Substitute occurrences of "-2018" with "-2020" using:
  git grep -I -l -e '-2018' -- ':(exclude)*.bak' | xargs \
  sed -b -i -e 's/-2018/-2020/g'

- Update special cases:
  CUEPlayer
    git grep -I -l -e 'Grigory Chudov 2010' -- | xargs \
    sed -b -i -e 's/Grigory Chudov 2010/2010-2020 Grigory Chudov/g'
