Check the supported authentication methods before login (SSH2)

Modified to confirm the available authentication method for the server prior to login and invalidate unsupported method.
Modified to access the server by using only user name in background when displaying authentication dialog. In order for this feature to work, user name must be identified when a connection request is started. If user name is specified in a default user name or in a command line, it will be used.
If a focus is lost after user name is entered, a content of user name field is used and it can't be changed afterward.
