Minor fix to Widget Wizard to include the disabled sprite for a UIImageButton

[bkevelham]

I don't know if this has already been reported (I couldn't find it) but the Widget Wizard for a UIImageButton has a minor issue after the inclusion of a disabled sprite.

The disabled sprite is not actually set for the UIImageButton. The culprit is a single missing line in CreateImageButton in UICreateWidgetWizard.cs

1. ib.disabledSprite = mImage3;

Adding that should do the trick.
