Missing method on SpAbstractWidgetPresenter to update the visual state that depends on the enabled block

[koendehondt]

See #1559.

Given that SpAbstractWidgetPresenter>>#enabled: can take a block:

enabled: aBooleanOrValuable
	"Set if the widget is enabled (clickable or focusable).
	This can either be a boolean or a block returning a boolean."

	enabled := aBooleanOrValuable

as in:

presenter := SpPresenter new.
button := SpButtonPresenter new
	icon: (presenter iconNamed: #smallSave);
	enabled: [ false ];
	action: [ "do something" ];
	yourself.
presenter layout: (SpBoxLayout newLeftToRight
	add: button;
	yourself).
presenter open

SpAbstractWidgetPresenter should have a method, e.g. refresh, to update the visual state of an instance, so that the condition in the enabled block is evaluated again.

Koen I thought about introducing a tag for book. What do you think? Like that we can help esteban knowing that this is important for the book.

Very good idea.
