Differentiate closing dialog from rejecting it with "no"

In confirmation dialog, the result is the same if I click "x" to close dialog as well as when I click "no" button. It would be more than useful to tell if user clicked one or another. Example would be "accept invitation" dialog. You can either: click yes (accept invitation), click no (reject invitation), close dialog (don't decide yet).

@mwtorkowski You're right. I'll add this to the TODO list. Thanks.
