Copyright notice added to remaining files

After doing a systematic search for files without a copyright notice, a few
more were found that didn't have a notice. So a notice was added for them.

I used this Bash command to find the files:

for f in $(find ./ -type f); do \
  if [[ $f != *.git* ]]; then \
    n=$(grep -i copyright $f | wc -l); \
    echo "$n $f"; \
  fi; \
done | awk '$1==0'
