HIGification of dialog boxes

[Krzysztof Foltman <kfoltman onet pl>]

As someone from #usability noticed, most in dialog boxes in Dia are 
completely HIG-uncompliant button order-wise. I could try to do the 
gruntwork and fix them, but I'm not sure if I should make attribute 
dialogs instant-apply (with only Close button) or explicit apply (Try, 
Cancel, OK).

Any opinions ? (I'd go for instant apply, as changing attributes or 
defaults for attributes is not - in my opinion - "irreversible, 
destructive or otherwise inconvenient to the user").

PS. Lars, are you going to review my two most recent patches in current 
form, or you're waiting for the zoom improvement too (which is better 
added later IMO) ?
