Rename IFWL_ListItem to CFWL_ListItem

Rename IFWL_ListItem to CFWL_ListItem

This CL removes the empty IFWL_ListItem class and uses CFWL_ListItem in its
place. As well, the CFWL_ComboListItem is removed and replaced with
CFWL_ListItem.  These were almost duplicate classes and the one missing field
added to CFWL_ListItem.

These were shadowed before, hopefully there is no issue with replacing. If there
is, it should be fixed by renaming instead of shadowing.
