xenadmin/XenAdmin/Actions/GUIActions/DeleteAllAlertsAction.cs
Konstantina Chremmou e3896239df CA-339305: XenCenter was hanging when update alerts were removed very fast, and other issues:
- Use a plain list to store update alerts and, where possible, fire a collection
  change event only after a bulk change and not every time a single object is added
  or removed.
- Fixed issue where dismissed updates were stored in the config of all connected
  pools, even of those where the update did not apply.
- Corrected RBAC checks for update dismissal.
- Fixed enabled state of dismiss buttons.
