Daniel Gibson 66ed216ad8 Update zip code to minizip 1.1
.. 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.
