Support the functional layout properties for LazyListMorph in tool-builder specs. Chose "alignment" instead of "positioning" because specs are not Morphic-specific. The terms "item" and "column" reflect item- or column-specifc settings, which can be confusing because our current lists do only support uniform (item) rows.
