PSCP now uses the modern SFTP protocol if it can, and falls back to

scp1 if it can't. Currently not very tested - I checked it in as
soon as it completed a successful recursive copy in both directions.
Also, one known bug: you can't specify a remote wildcard, because by
the nature of SFTP we'll need to implement the wildcard engine on
the client side. I do intend to do this (and use the same wildcard
engine in PSFTP as well) but I haven't got round to it yet.
