When renaming an alias that is referenced by other aliases make the propper ajustements to reflect the changed name.

Remove the nat_server pages they are never used and unnecessary!

Fix typo

• If editing an alias do not display itself on the autocompletion list
• Prevent that the user mixes wrong type of aliases, only host and network type mixing is allowed. Openvpn may be added later on too.
• Instead of checking for nested loops when unwinding aliases just prevent the loops. It is easier and allows some rare cases when nesting is needed.

Make matching on autosuggestion case insensitive.

Remove unused code.

Add my copyright i have done the necessary work on aliases.
