[GREENFOOT-440] Method header is fuzzy on Mac Retina when pinned
We used an Image because I was worried at the time (if we relocated the actual method header) about making the fields read-only and masking the mouse events. I think we now know enough JavaFX that we can sort out all those issues, and using text avoids blurriness and some other layout problems which occur on first load.
