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

one wasn't compatible and written in a strange style).

+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.
