Copied over the ListItem.h header with the original one for now (the old

/** class BListItem : public BArchivable {
* A BListItem represents a single item in a BListView (or
* BOutlineListView). The BListItem object provides drawing
* instructions that can draw the item (through DrawItem()), and
* keeps track of the item's state. To use a BListItem, you must
* add it to a BListView through BListView::AddItem()
* (BOutlineListView provides additional item-adding functions).
* The BListView object provides the drawing context for the
* BListItem's DrawItem() function.
*
* BListItem is abstract; each subclass must implement DrawItem().
* BStringItem—the only BListItem subclass provided by
* Be—implements the function to draw the item as a line of text.
