Add a left/right option and a scroll bar to a menu created

msaunders3127

Right now a new vertical menu created can only be arranged with included pages displayed to the right - it needs a left/right optiion and also any pages, if the page list is bigger than the stage or at the bottom of the section menu, need a scroll bar (similar to a TOC), otherwise they are displayed off the stage and are unreachable.

@msaunders3127 This issue has been put in as an enhancement request for the menu object.
