App icon scaling incorrect in SUUpdateAlert

[nriley]

My app icon is a solid colored rectangle, so there's no point in making a larger icon. Almost everything handles this correctly — except Sparkle’s update window.

I'm happy to fix this since it seems pretty simple by changing the image cell scaling to NSImageScaleProportionallyUpOrDown. I couldn't figure out if Sparkle had a way of automatically producing the xibs, or if I should edit each localized xib individually.

Thanks.

We don't generate XIBs. I suppose it can be done with find'n'replace on all XML files.

Thanks, done. (Merged #764).
