Add one-click ACk link column to Alerts widget

We would like to see a column in the Alert widget which can be used to perform a one-click acknowledgement of the alert.  Perhaps  the severity column could double as this function since it already shows a check mark for acked alerts?  If it is an extra column, then the column should not take up too much real-estate, so perhaps use small icons as the ack link.

Opening each alert to ack requires 3 mouse operations, and is frustrating if the Alert widget refreshes while an alert property view is open, since it immediately disappears.

We have a need to quickly acknowledge lots of alerts.  In the Alerts page there are selection checkboxes, but the Alerts page lacks a global system wide filter to enforce the same view for all operations staff.
