SSH2: make it so negotiated algorithms can be seen before login

* terrafrost/ssh2-show-methods-before-login:
  SSH2: white space adjustment
  SSH: update getServerPublicHostKey() to use new _connect() method
  SSH2: fix if statement for conditional _connect() call
  simplify calls to $this->_connect()
