Oct-2009 - Mathias Svensson - Added zipRemoveExtraInfoBlock to strip extra field data from its ZIP64 data
It is used when recreting zip archive with RAW when deleting items from a zip.
ZIP64 data is automaticly added to items that needs it, and existing ZIP64 data need to be removed.
Okt-2009 - Mathias Svensson - Added support for BZIP2 as compression mode (bzip2 lib is required)
Oct-2009 - Mathias Svensson - Added support for BZIP2 as compression mode (bzip2 lib is required)
Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer
