patch

This is because the shell view control is ANSI, so the listview sends
LVN_GETDISPINFOA instead of LVN_GETDISPINFOW to get the item name. This patch
makes the classes Unicode and fixes some other W->A conversions. ANSI is still
used for sorting and in some parts of menu building. If there are no visible
regressions caused by this patch I can divide it into smaller parts and send it
to wine-patches.
