PHP configuration variables for scripts cannot be 'none'

If the option "PHP configuration variables for scripts" is set to "none", Apache dies due to:

Syntax error on line [some line] of /usr/local/apache2/conf/httpd.conf:
php_value takes two arguments, PHP Value Modifier

Virtualmin puts 'php_value none' into the httpd.conf file, which is improper syntax. I _think_ leaving out the line entirely would be the correct fix. You guys probably know better than I do though.

I am running Virtualmin 3.19, Apache 2.2.3 and PHP version 5.1.5. (Yeah I know it's an old Virtualmin version, but the updates page didn't include a note about this problem being fixed so I assume you don't know.)
