some unsigned/NSInteger to NSUInteger changes in -gui

[Sebastian Reitenbach]

Hi,

while looking at compilation warnings from the latest releases, I found in -gui 
(svn) some parts in NSTableView that would need to be changed. First is easy, 
declare i as NSUInteger (was unsigned before). Further I think _selected_item 
declared in the header as NSInteger also should be a NSUInteger.

is it OK when I commit the patch?

Sebastian
