Clean up the API logging code:
      - Try to reduce logging to one line per function call instead of tw
      - Put all arguments & their values into log for calls
      - Add 'this' parameter information to function call logging, making it show the appropriate
        internal pointer (this.obj, this.sp, this.ap...)
      - Clean up some return values
      - Remove logging of constructors that construct empty objects
      - Change '==>' to '=>'  for showing result values...
      - Fix various minor bugs
      - Add some protected 'get' functions to help getting the internal pointers for the 'this' arguments...
