ssh.exe fails to add host to list of known hosts

Repro

• Setup new keys on server
• Open ssh session (prompts to accept/reject the new key)
• say "yes"
• ssh.exe complains:
  Failed to add the host to the list of known hosts (.ssh/known_hosts)

Updated code to GitGub to fix it. .ssh directory in the user's home directory were not created and thus known_hosts file could not be written. Please test it and then close it if the fix works in your setup.

Verified.
