Unpack zip, skip files already there

[KoalaBear]

I first uploading a single file.

After that I zipped more files from the same directory and uploaded that as a package, including the file I already uploaded.

Subsonic stopped the moment it tries to unpack the existing file.

Would be nice if Subsonic just skipped the file (and notice it in the unpack log) and continues.

Thanks in advance.
