Additional list mode

We have numbered, bullet and plain list. It would be nice to have another list function that allows a vertical lineup of whatever is fed to this new “VerticalList()” function. There are some workarounds, but if we want to make a vertical list of Coda objects, they become text items, which is not always a desired solution. A bullet list also strips Coda objects of all the information that an object normally has, and that could be improved too.
