Focus style for dialog buttons (cancel,ok) is too heavy

[Piotrek Koszuliński]

This 2px dark grey border isn't a problem when user intentionally focus button (by tabbing). But it's confusing in dialogs like "about", because "cancel" is focused by default. It looks strange there.

I think that 1px width border is better, because it's more natural in this skin. What's more - I like that blue color for focus in e.g. smileys - it shows that something is active/focus, not just hovered. In my opinion it's a good help distinguishing user between these states. So maybe buttons may have the same border on focus/active.

It's like a template:

• light grey for normal,
• darker grey for hover,
• color for active/focus.
