Swedish translation done

Thanks to Malin Nilsson, we have a Swedish translation of StitchMinder in addition to the Japanese translation. I've also added the ability to "undo" a count -- simply touch the counter that you want to undo and drag to another counter before lifting your finger. It takes a little practice, but once you get the hang of it, it is very quick and doesn't require another button on the screen. The updated application has been sent to Apple for review, so it should show up in the App Store in about a week to ten days.
