Option to ignore warning about .htaccess contents

While experimenting with different rules in my htaccess I've had numerous complaints from nagios informing me that boost had a problem. On the status page this is detailed in a message about the contents of my .htaccess file.

Since I know the .htaccess contains something valid I would like to suppress these warnings.
I know that in a perfect world I wouldn't have to manually modify the htaccess code, but thats another patch I'm working on ;)

Anyway I introduced a checkbox... hope you find it useful.
