Listview ignores the user specified image state index

Now I know why I did that. Documentation from LVM_INSERTITEM says:
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/commctls/listview/messages/lvm_insertitem.asp)
...
If a list-view control has the LVS_EX_CHECKBOXES style set, 
any value placed in bits 12 through 15 of the state member of 
the LVITEM structure will be ignored. When an item is added 
with this style set, it will always be set to the unchecked state.
...

Documentation for LVITEM.state, says:
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/commctls/listview/structures/lvitem.asp)
...
Bits 12 through 15 of this member specify the state image index. 
The state image is displayed next to an item's icon to indicate 
an application-defined state. If these bits are zero, the item 
has no state image. To isolate these bits, use the LVIS_STATEIMAGEMASK 
mask. To set the state image index, use the INDEXTOSTATEIMAGEMASK 
macro. The state image index specifies the index of the image in 
the state image list that should be drawn. The state image list is 
specified with the LVM_SETIMAGELIST message.
...

So I guess we need to clear the bits only if LVS_EX_CHECKBOXES is set.

ChangeLog
    Clear the state image bits only if LVS_EX_CHECKBOXES is set.
    Fix obvious logical error in focus handling.
    Indentation and formatting fixes.
    (based on a patch by Krishna Murthy).
