Fixed bug that caused crash on adding an item to any area in a snippet and possibly elsewhere. The initialContent option used to display inline instructions in an area is now expected to start with <p data-initial-content>, otherwise your initialContent gets wrapped in such a p tag automatically. This allows safe and reliable detection and removal of the initial content. Also the initial content is removed correctly when you start editing, not just when you add an item; remember, some areas are text only, and some people click on the initialContent rather than hitting the add content menu.
