Huw Davies 861282bf28 Fix the icon resource ids (most were off by one). 
Fix IExtractIcon_{GetIconLocation,Extract} to use -ve icon resource
ids and fix bugs relating to confusion between resource ids and the
system imagelist indicies.
Extend the system imagelist initialization hack to load both +ve and
-ve resource ids.
Add a printer icon (that'll be used by an upcoming printer folder
patch).
