MINIFICPP-1203 fix whitespaces around comments, remove redundant comments

Script used to correct linter reported missing space between // and comment:
make linter |& egrep -v '^Done processing|^Ignoring' | grep "Should have a space between // and comment" | tr ":" " " | cut -d" " -f1,2 | sort -rn -k1 -k2 | xargs -n 2 sh -c 'sed -i "" "$2s;//;// ;" $1' sh

Script used to correct linter missing whitepaces between code and comments:
make linter |& egrep -v '^Done processing|^Ignoring' | grep "At least two spaces is best between code and comments" | tr ":" " " | cut -d" " -f1,2 | sort -rn -k1 -k2 | xargs -n 2 sh -c 'sed -i "" "$2s;//;  //;" $1 && sed -i "" "$2s;   //;  //;" $1' sh
