Wine upgraded to 1.5.22

This version includes the new experimental Mac driver which means it can be
run without X11. As the driver is still incomplete and buggy X11 is still the
default and instructions on how to switch are included in caveats.

libpng, libtiff, little-cms and xz (liblzma) are modified to always build as
universal binaries like the jpeg and libicns packages already do. These
changes are required if wine is to be able to use them for 32-bit windows
applications.
