Retrieves the path of the image file used to represent a given state.
path = getStateImg(state);
The path of the image file is returned.
Regardless of whether the image is the built-in state image, or a custom image set through the STATEIMG element, the returned path name includes the required path for TQS to display the image.
myImgEl.src = getStateImg("DONE");
myImgEl.src = getStateImg(getCurLocState());
