RemoteLinux: More preparations for introducing an abstract device class.
- Introduce clone() method. - Rename "osType" to "type" and "deviceType" to "machineType". - Move machine type display out of generic settings widget. - Put only immutable attributes into the device constructor and set the others via setters. As part of this, also give the SshConnectionParameters a default proxy type. The necessity to give one to the constructor explicitly was for historical reasons.
