External Storage Support - FTP port not extracted from host field to port key

[nobilisgkill4]

When you create a External Storage via FTP in the UI and enter the full adress (hostname:port) in the host field it is saved in the storrage configuration key host. The External Storrage provider for FTP expeced only the hostname in the host key and the port in the port key.

There is no automatic split / seperate field in the web UI. When you change the configuration manualy via OCC it works as expected.
