The current behaviour of protecting a folder only modifies adds the
relevant .htaccess configuration lines if the file doesn't already
exist. In the case that it exists, no change is made and it appears to
"not work" for users.
This commit improves the feedbackup to users about what is happening,
and gives them the necessary information to modify their custom
.htaccess file with the appropriate configuration lines.
