was available for non-dismissible alerts. Fixed wrong enabled state of the top ToolStripSplitbutton Dismiss on the alerts and the events page. Refactored code calculating dismissability of alerts and dismissing them. Events list should be multi-selectable. Signed-off-by: Konstantina Chremmou <konstantina.chremmou@citrix.com>
