InputfieldPageListSelect: Separate out labels

[stuartsa 1]

Can you please consider improving InputfieldPageListSelect (and InputfieldPageListSelectMultiple) by separating out the labels of the tree nodes from the label of the output? I use "{parent.title}: {title}" as a custom label algorithm. However, that is just to provide context when the field value is displayed in a PageTable. When actually selecting nodes, the labels "{parent.title}: {title}" on ALL of the nodes in the tree is just sugar. It should definitely not be shown on nodes that are not leaves, for instance. Thank you!
