Lion compatibility: no Sites folder by default

[eykanal]

The script assumes that the Sites folder exists, which is no longer a safe assumption in Lion; in 10.7, it only is there if the user turns on the "web sharing" option in the Sharing section of the System Preferences. I didn't check to see whether there were any other lion incompatibilities.

Perhaps I am wrong.. but seems this script is not optimised for Lion/Mountain Lion at all..
It looks for virtualhosts into $APACHE_CONFIG/virtualhosts, when it should be $APACHE_CONFIG/extra/ or $APACHE_CONFIG/extra/httpd-vhosts.conf

[star-szr]

$APACHE_CONFIG/virtualhosts is created by this script and included from httpd.conf. This allows for the structure of having one file per virtualhost and makes things like virtualhost.sh --list and virtualhost.sh --delete much more straightforward behind the scenes.

At a glance it does look like we might want to add some error handling if $DOC_ROOT_PREFIX (defaults to the Sites folder) doesn't exist.
