Fixed bug #208

So, here's a patch with a reimplementation of QZ_SetIcon() that does what I
described above. I apologize for the delay, I've been quite busy in the last
few days.

It appears to work here on 10.4.5 PPC in the limited testing that I've done;
I'll try to test it on 10.3.9 and 10.2.8 as well, but that might take another
week or so. Please test on i386.

Regarding alpha channels, per-surface alpha, and color keys, the same semantics
as for regular blits to an RGB surface should apply (for the final icon
composited onto the dock), unless I made a mistake - except in one pathological
case: if the icon surface has an alpha channel, its SDL_SRCALPHA flag is not
set (i.e. it has been explicitly cleared, since it's on by default for RGBA
surfaces), and it has a color key, plus an explicit mask was specified (instead
of the one autogenerated from the colorkey), then the color-keyed areas appear
black instead of transparent. I found no elegant way of fixing this, was too
lazy to implement the inelegant one, and decided that it isn't worth the effort
(but if someone disagrees, I can do it).

     2 The latest development version of SDL is available via Subversion.
     3 Subversion allows you to get up-to-the-minute fixes and enhancements;
     4 as a developer works on a source tree, you can use svn to mirror that
     5 source tree instead of waiting for an official release. Please look
     6 at the Subversion website ( http://subversion.tigris.org/ ) for more
     7 information on using svn, where you can also download software for
     8 MacOS, Windows, and Unix systems.

    12 If you are building SDL with an IDE, you will need to copy the file
    13 include/SDL_config.h.default to include/SDL_config.h before building.
    14 
    15 If you are building SDL via configure, you will need to run autogen.sh
    16 before running configure.
