fixed #8 width and height properties of FiretypeStarlingTextField.as are now updated correctly.
- Using the scaleX and scaleY properties on FiretypeStarlingTextField.as will now affect the width and height properties correctly.
- Using the textScale property of FiretypeStarlingTextField.as will only scale the characters of the text. The width will be kept the same until separate words become wider than the entered width. The height might change dependent on word wrap.
