The default value for Ti.UI.IOS.Stepper.value is null, when it should be 0 according to: https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIStepper_Class/index.html#//apple_ref/occ/instp/UIStepper/value
Steps to Reproduce Issue:
1. Create a new Alloy project
2. Use the below code to demonstrate the issue
3. Run the project and click on "OK"
The value is output as null
The value is output as 0
This impacts trying to decrement the stepper on first click. Trying to increment the stepper sets it to the step value.
