- Added incremental sql query collection file to make merging easier and avoid high patch file count

- 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.

(in incremental sql-files this was already done in upd_0064.sql)

- Enable php-fpm socket mode as default.

- Updated version number to 3.0.5.4rc1
