.. from zlib-1.2.7/contrib/minizip/ It resides next to the unzip code in framework/minizip/ This updates makes the code a bit cleaner and creating zip64 with the idZipBuilder is now more feasible and update to future minizip versions should be easier as I didn't change the original files from minizip 1.1 very much.
