- Make sure ISPConfig shows the correct error message (instad of an SQL error) when a website is renamed after an alias domain that still exists.
- It should be possible to create two websites with the same domain on the same server as long as the IP differs. I therefore changed the serverdomain index of the web_domain table to include the IP address.

- Fixed "no_domain_perm" error when trying to add proxy directives for subdomains or alias domains (nginx).

- Fixed: nginx placeholders could not be added to directive snippets textarea by clicking on the link.

Fixed regex in prefix validation under System > interface config that prevented numbers in prefixes.
