Accelerators for alert/confirm/etc

[djMax]

I see that ESC is bound as an accelerator on alert/confirm, but Y and N are not, and also Tab doesn't cycle between JUST the two buttons. Should we fix this? If I were to add my own key map, will that automatically remove itself when the dialog goes away?

I've extended Ext to bind y & n while a confirm is active. The code is quite simple, you literally just bind the keymaps before showing the confirm, then get rid of them just after you hide it.

evant it would be nice if you share the code with others :)
