<Swing Dev> RFR: 6251901: BasicTextUI: installDefaults method are contrary to the documentation

[Prasanta Sadhukhan]

BasicTextUI: installDefaults javadoc specifies only font, foreground and background properties are set  if their current value is either null or a UIResource
and other properties are set if the current value is null
but in reality all properties such as font, foreground, background, caret color, selection color, selected text color, disabled text color, and border color are set if their current value is either null or a UIResource.
Fixed the javadoc to specify the same.
