.wsz skins cannot be used on Windows
The current scheme uses the external "unzip" program which generally isn't present on Windows.
We could ship an "unzip.exe" along with the Windows build, but it would be better if we could read the .wsz/.zip files directly through the VFS layer, without running an external .exe and creating temporary files on the C: drive.

It is possible to handle directly ZIP files on Windows with some API, but in my opionion, since Audacious is already released with zLib, perhaps it would be worth to just import the small unzip.c and unzip.h from zlib sources, into contrib/minizip:
and free all platforms from the dependency to an external tool.
In this way, the skins will be loaded directly in memory from the ZIP file, without the need to unpack them on disk, like you said.
