Add some commentary in #userInterfaceTheme so that people can figure out what to do when a property (e.g., color) does not look as expected and they managed to track down the call to #userInterfaceTheme in the source code.

Item was changed:
  ----- Method: Object>>userInterfaceTheme (in category '*System-Preferences') -----
  userInterfaceTheme
+ 	"Call this to conveniently access properties from the current user interface theme. NOTE THAT if you want to change a property in the current theme, you can either modify its entry in the property dictionary directly (see #set:for:to:) or locate its initialization code, which is usually in a subclass of UserInterfaceTheme. For example SqueakTheme class >> #addScrollables: describes UI properties around widgets that can scroll such as text fields. After modifying the init code, you have to re-initialize the theme again via UserInterfaceTheme class >> #cleanUpAndReset."
