Fix terrain layering bug.
added dandelions to the field.
major refactoring to websocket / field handler.
"Solar system" script, will calculate the slope and render based on it.
Some improvments, now the intensity is determined by the slope, as before, AND the distance to the object from the observer.
Allow for tile layer for future effects.
