ESB Editor - Notifier action needs ability to add targets to a notifier list

For the Notifier action, we need the ability to add targets to a notifier list.

For example, a NotificationList for an error notifier (see page 119 of Progammer's Reference for ESB 4.7):

<NotificationList type="err">
<target class="NotifyConsole" />
<target class="NotifyFiles" >
<file name="@results.dir@/badresult.log" />
</target>
</NotificationList>

I'm not sure how we'd implement this for 3.1 since it's pretty detailed - there are multiple types of targets for the NotifyList:

• NotifyConsole
• NotifyFiles
• NotifySQLTable
• NotifyFTP
• NotifyQueues
• NotifyTopics
• NotifyEmail

I'm open to suggestions here.
