 * Loads any custom widget or URL based on the given parameters.
 *
 * The currently active idSite, period, date and segment (if needed) is automatically
 * appended to the parameters. If this widget is removed from the DOM and requests are in
 * progress, these requests will be aborted. A loading message or an error message on failure
 * is shown as well. It's kinda similar to ng-include but there it is not possible to
 * listen to HTTP errors etc.
 *
 * Example:
 * <WidgetLoader :widget-params="{module: '', action: '', ...}"/>
