[project @ Arch-1:robey@lag.net--2003-public%secsh--dev--1.0--patch-41] 

make get_remote_server_key() return a PKey object
a good suggestion from roger binns: make get_remote_server_key() just return
a pkey object instead of a tuple of strings.  all the strings can be extracted
from the pkey object, as well as other potentially useful things.
