TextStyle.setStyle & TextStyle.setFont now set fontSize, fontStyle & fontFamily when font is a string

TextStyle.setFont now sets fontFamily, fontSize, and fontStyle when "font" is a string. 
TextStyle.setStyle calls TextStyle.setFont when "font" is overridden.
This fixes an issue where TextStyle.update(true) overrides TextStyle._font
