config option to select a private keyfile from pageant per server

[Axel Huizinga]

Actually filezilla seems to accept only the private keyfile stored in the default settings from putty. The log shows that it checks only this one and not all keys added to pageant - so I always have to change putty's default settings if I want to access a server with a different keyfile. It will be more convenient to allow the preselection of the keyfile in the servermanager for each account separately. Maybe this could be achieved in a similar way like pscp which accepts a commandline like this one which I use from a perl script to update a file directly from an SciTE or Geany: pscp.exe -i keyfile -l user "localpath" host:remotepath. If the keyfile is loaded in pageant it will be used without an additional passphrase request.
