+   * Configuration-Options for jQuery.openx
+   *
+   * Since the domain-name of the ad-server is the only required parameter,
+   * jQuery.openx for convenience can be configured with only that one
+   * parameter. For example: "jQuery.openx('openx.example.org');". If more
+   * configuration-options are needed, they must be specified as an object.
+   * For example: "jQuery.openx({'server': 'openx.example.org', ... });".
+   *
+   *
+   * Server-Settings:
+   *
+   * server:        string  Name of the server, without protocol or port. For
+   *                        example "openx.example.org". This option is
+   *                        REQUIRED.
+   * protocol:              Optional parameter.
+   *                http:   All connections to the ad-server are made via HTTP.
+   *                https:  All connections to the ad-server are made via HTTPS.
+   *                        If empty, document.location.protocol will be used.
+   * http_port:     number  Port-Number for HTTP-connections to the ad-server
+   *                        (only needed, when it is not the default-value 80).
+   * https_port:            Port-Number for HTTPS-connections to the ad-server
+   *                        (only needed, when it is not the default-value 443).
+   *
+   *
+   * Delivery-Options (for details and explanations see the see:
+   * http://www.openx.com/docs/2.8/userguide/single%20page%20call):
+   *
+   * block:         1       Don't show the banner again on the same page.
+   *                0       A Banner might be shown multiple times on the same
+   *                        page (DEFAULT).
+   * blockcampaign: 1       Don't show a banner from the same campaign again on
+   *                        the same page.
+   *                0       A Banner from the same campaign might be shown
+   *                        muliple times on the same page (DEFAULT).
+   * target:        string  The value is addes as the HTML TARGET attribute in
+   *                        the ad code. Examples for sensible values: "_blank",
+   *                        "_top".
+   * withtext:      1       Show text below banner. Enter this text in the
+   *			    Banner properties page.
+   *                0       Ignore the text-field from the banner-properties
+                            (DEFAULT).
+   * charset:       string  Charset used, when delivering the banner-codes.
+   *                        If empty, the charset is guessed by OpenX. Examples
+   *                        for sensible values: "UTF-8", "ISO-8859-1".
