Configuring default action views dynamically

Attributes of default action views can be changed dynamically during a dialog execution with ui.Dialog.setAction*() methods.

For example, to change the text and icon of the default action view bound to the "print" action:

CALL DIALOG.setActionText("print", "Print order" )
CALL DIALOG.setActionImage("print", "printer" )

The corresponding default action view will be decorated with the new text and icon.
