Updated index.php

Hi there, I have been working with the latest development version of kannel downloaded from its svn server and am using your kannel-ui for viewing traffic. kannel-ui seems to be working very well but with two minor issues in the SMSCS table:
1. The "START" and "STOP" buttons under "Action" always lead to "Invalid Command" when pressed.
2. The SMS/DLR Received/Sent info are not displaying.
I did a quick fix in index.php to get it working, so please review it when you have time. Thank you very much.
