Patch - Use an alert box when actions aren't supported

[Ken VanDine <ken.vandine@canonical.com>]

[-- Attachment #1: Type: text/plain, Size: 383 bytes --]

The attached patch checks if the notification daemon supports actions,
and if it doesn't display an unfocused alert box instead.

For more information:

And the downstream bug report:
