    The Google Mail plugin allows you to send a mail notification from your Google mail
    account by performing an \l{Action}.

    ATTENTION: The password currently will be saved as plain text in the guh configuration file.

    \section1 Examples
    \section2 Adding a Google Mail Notification service
    In order to add a Google Mail Notification service you need to configure
    the "Google Mail login" (user), the password for your Gmail account and the address
    of the recipient.
    \code
    {
        "id":1,
        "method":"Devices.AddConfiguredDevice",
        "params":{
            "deviceClassId": "{38ed6ffc-f43b-48f8-aea2-8d63cdcad87e}",
            "deviceParams":{
                "user":"my.address@gmail.com",
                "password":"my_secret_password"
                "sendTo":"recipient@example.com"}
            }
        }
    }
    \endcode
    Before the device will be added, the plugin trys to login. If the username or the password
    are wrong, an error message will be send.
    \code
    {
        "id": 1,
        "params": {
            "deviceId": "{0b99ea27-896a-4a23-a044-3f1441f6a9a7}",
            "errorMessage": "",
            "success": true
        },
        "status": "success"
    }
    \endcode
