Use existing Putty connections

It would be a great feature if Sftpdrive could use existing Putty connections instead of the manual connection setup within Sftpdrive, i.e. you would only have to specify the name of the Putty connection in Sftpdrive. TortoiseSVN demonstrates this very nicely with the svn+ssh - protocol. They use Plink for the connection, which naturally has access to Putty's connections and provides the whole Putty feature set, including proxies and authentication agent support.
