quickly select all items in a listview

When you hit Ctrl-A in a listview control, the control loops through every
single item in the list selecting them and setting focus on the item. With tens
of thousands of items, this takes a _long_time_.

I've created a patch that sets the range of selected items. This select all
happens much more instantaneously. As an added bugfix, the selected item will
not be changed when all items are selected.
