Clean up raw CONTRIBUTED-BY output into something nicer looking

fixup-contributed-by.py

# The raw CONTRIBUTED-BY file was generated by editing all files to remove the
# Contributed by lines and then running the following command:
# 
# git diff -U1 | grep "^-" | sed -e 's/--- a\/\(.*\)/\1:/' -e 's/^-\(.*\)/\1\n/' >> CONTRIBUTED-BY
