Update UI widgets to support dynamic changes to input ranges

There are cases where DynamicPlugins would like to update their associated UI widgets to reflect current data ranges. For example, if you want to delete an axis the allowed range of the plane to keep changes when you select a new axis. These range changes are currently not supported.

Update the various UI widgets to support dynamic changes. We could start with Swing only for now and add others in a later cycle.

The specific code changes required touch ChoiceWidgets and NumberWidgets. For each a range of values could grow or shrink. We need to update refreshWidget() for these classes.

In refreshWidget() we can get min, max, or set of values, compare to current, and update as needed. It's important to update scrollbar, spinner, and slider ranges to reflect new value ranges.

Note we might have to set min, max, and value in one call because the widgets can get unhappy if you try to set one of these outside a value consistewnt with the others.

Note: a workaround of this issue was put in place in DeleteAxis. It has a callback that always clamps the position to the current axis range. It works for now. It has one gotcha. One can enter a value that is out of range via the keyboard and then select OK with the mouse. When the value is out of bounds the plane position used is the nearest endpoint. This could be unexpected behavior for the user. Make sure we address the ticket for beta2.
