Return a list of authentications supported by SSH1 server.

Just because a cipher is supported by an SSH1 server doesn't mean it's supported by this library. If $raw_output
is set to true, returns, instead, an array of constants.  ie. instead of array('password authentication'), you'll
get array(self::AUTH_PASSWORD).

@param bool $raw_output
@return array
@access public
Return a list of authentications supported by SSH1 server .
