Add Password Encryption.

The Eurex exchange provides a public key that traders use to encrypt their passwords before sending them over the network. The Handler now supports password encryption. To encrypt a password, use the `Handler.encryptPassword` method and new `Handler.connect` method that accepts `LogonRequestEncrypted`.

Remove `HandlerSettings`'s properties.

The following properties are removed from the `HandlerSettings` class:

- `gatewayPassword`; - `partyIdSessionId`.

Set these values directly in the `LogonRequest`.
