Finished the implementation of LISTVIEW_SetColumnWidth. Tested

Browse source 
against windows thoroughly.  Fixed bug resulting in unsigned values
being passed into LISTVIEW_SetColumnWidth from the listview window
procedure.  Fixed LISTVIEW_GetItemHeight to disregard the height of
icons if no icons exist.
