Step Node

Here I'm not proposing a new node, so much as, new option for the "knob" widget.

There are a lot of instances where it is desirable to dial through number at a
set increments, eg 15 degrees steps of rotation.
One example that arises often is for only even or only odd numbers.

The work-around for achieving this result is not difficult, but it is clumsy compared to
having the graduations builtin.
