UI Enhancements: Scan Progress Dialog

When in the midst of an active scan, you can click on the 'Show scan progress details' button to bring up this dialog. I 'd like to request a number of small improvements:

1. Add a column at the right called "Alerts" and the value for each row in that column is the number of NEW alerts identified during the run of that plugin.
2. Enhance the Status column to have both a pause button and skip button for the currently running plugin. (It already has a skip button)
3. Enhance the Status column to have a remove Plugin from this scan button (an X button) for all plugins that haven't run yet.
4. To reduce load (slightly), change the Elapsed column to only count down seconds. I think milliseconds is a bit silly.
5. When a scan is paused (either via the new feature in #2 above, or via the pause button on the Active Scan tab, I think the elapsed time should pause too (i.e., not keep advancing while paused).

Start at the “Show scan progress details” dialog and the pause control on the Active Scan tab. Review how plugin rows, status actions, elapsed time, and new alerts are currently represented; done means all five requested dialog and pause-state behaviors work together.
