Fix loading icon from resource

[Maxime Bellengé]

Some icons were not loaded correctly sometimes. I found it came from the
fact we must use the wBitCount field of CURSORICONDIRENTRY instead of
the bColorCount. 
Actually, bColorCount is 0 if >=8bpp (see
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnwui/html/msdn_icons.asp )

Now all the icon in the tabs are displayed correctly in emule :) (and in
many other apps I think).
