12 Changes
13 Oct-2009 - Mathias Svensson - Remove old C style function prototypes
14 Oct-2009 - Mathias Svensson - Added Zip64 Support when creating new file archives
15 Oct-2009 - Mathias Svensson - Did some code cleanup and refactoring to get better overview of some functions.
16 Oct-2009 - Mathias Svensson - Added zipRemoveExtraInfoBlock to strip extra field data from its ZIP64 data
17 It is used when recreting zip archive with RAW when deleting items from a zip.
18 ZIP64 data is automatically added to items that needs it, and existing ZIP64 data need to be removed.
19 Oct-2009 - Mathias Svensson - Added support for BZIP2 as compression mode (bzip2 lib is required)
20 Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer
