Small awstats improvements

[BioALIEN]

I still believe we need to lock the stats directory out of the box. AWStats are all about having meaningful stats. The admin, the stats directory, cgi-bin directory, tmp directory etc are not part of it. If you are studying your site's stats, you want statistically meaningful analysis. This argument becomes flawed if you're looking at traffic that's not part of the "site" or "subdomain".

I hope I got my point across
