- nginx: changed /awstats-icon location from "location /awstats-icon" to "location ^~ /awstats-icon" so that it isn't affected by any "location ~*  \.(jpg|jpeg|png|gif|css|js|ico)$" directive.

- Added an alias "/awstats-icon" for /usr/share/awstats/icon to the nginx vhost template so that images are displayed in the AWStats statistics on nginx.

- Added PHP-FPM pm settings (pm.max_children, pm.start_servers, pm.min_spare_servers, pm.max_spare_servers) to the "Options" tab of a website.

- Changed FastCGI buffers for ISPConfig nginx vhost because otherwise you get "upstream sent too big header while reading response header from upstream" on OpenSUSE.
- Added 502 error page ("Bad Gateway").
- Added "fastcgi_intercept_errors on;" to nginx vhost template so that ISPConfig's error pages are displayed instead of the default nginx ones.

- Added "ipv6only=on" to the IPv6 listen lines in the nginx vhost template to avoid "[emerg]: bind() to [::]:80 failed (98: Address already in use)" errors.

- Added SEO redirects (both Apache & nginx) to redirect from non-www website to www website or vice versa.
- Introduced placeholder [scheme] for redirect paths for alias and subdomains; will be replaced with http or https, depending on what the visitor uses.

- Fixed FS#1745.
