Adds support for ZIP files that include files that are symbolic links.
See the note in SSZipArchive.m for more information about that.
Includes a test that will probably only pass if you have GitHub for Mac
installed because that's the program I used as a test to symlink
against.
I created the symbolic link with 'ln -s /Applications/GitHub.app
SymbolicLink/GitHub.app' so I'm not entirely sure how it'll behave for
hard links, but I can't test that right now.
Fixes issues with files being truncated when their headers have values
that represent smaller uncompressed sizes then the actual data. This
generally fixes issues where the whatever program zipped the file
fucked up the headers. The fix makes ssziparchive behave like other
unzip utilities that ignore the header and decompress the actual data
until it's finished.
I've tested a bunch and all of the tests included pass, if any other
issues arrive I'd be glad to take additional time to look into it.
Includes a file, IncorrectHeaders.zip, that is a zip of a folder called
IncorrectHeaders which includes a single file, Readme.txt. I've
intentionally changed the header for that file to read 50 bytes intend
of the actual 59 for testing purposes.
