Feature Request: Ask if I want to save changes when I hit the "back"-arrow

[DamageIncorporated]

Hey,

I've just started to use Budget Watch and have found that I tend to accidently hit the back button or arrow when I have completed editing a transaction or budget.

BW then exits the edit dialog and I discard my changes instead of saving them. I wish BW would warn me at this point before I proceed ;-)
