- Added "Rewrite Rules" field to the "Redirect" tab so that customers can set rewrite rules themselves on nginx.

- Changed regex for redirect path (Web sites, subdomains, vhost subdomains, alias domains) and web folder (vhost subdomains) so that ".." is not allowed (in order to prevent path traversals).
- nginx: don't allow folders for proxy redirects (subdomains and alias domains); URL is required.
- nginx: modified rewriting.

- Disabled "fastcgi_param PATH_INFO $fastcgi_script_name;" in nginx vhost template (see http://gunblad3.blogspot.de/2009/07/nginx-php-fpm-serverphpself-returning.html ).

- Added PayPal email address field to client and reseller form.
- Added missing bank details fields to reseller form.

- nginx: merge function: default action is now to replace older locations in the nginx vhost configuration; a merge  instead of a replacement can be achieved by putting the string "##merge##" (without quotes) at the end of the most recent location line (e.g. "location ~ \.php$ { ##merge##").

- 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.
