Toilet

Update: subtle adjustment of toilet bowl to try and prevent sticking.
Added more test objects.

A toilet. Or bog. Or water-closet. Or s***shack.

When the tick is indicated, press F to flush. Press the otber buttons for test objects.

Unfortunately because principia works on a 2d- basis, getting the flush to attack from all angles is v.difficult, so the flush action isn't perfect.

In other words, just as in real life, you may face the unflushable!
