Enhance CMS monitor to auto page through message list.

[jdalbey]

We want the CMS monitor to run without user interaction. So the app needs to display all the CMS messages without the user having to scroll down the page. The app should be enhanced to automatically advance through all the messages, showing some fixed number of messages on each page and pausing the display for a certain number of seconds. There should be a caption indicating which page is currently being displayed, e.g., "Page 1 of 3". Make sure there is little or no "flicker" when the page changes.
It would be great if there was a way to dynamically modify the values for messages per page and seconds of display duration.

First draft reviewed on Tue July 16. Desired modifications:

1. Omit phase 2 if phase 2 msg is empty.
   
2. Expand display to 5 CMS messages.
   
3. Restrict HAR messages to one line.
   
4. Max of 3 HAR messages.
   
5. Add "Pg 1 of X" to "Active CMS Messages"
   
6. Reduce display duration for phase to 2 seconds.
