Rockbox Utility: Replace OSDaB Zip with QuaZip.
This change fixes problems with zip files created with newer zip utilities (a known issue is the iLike theme). QuaZip also allows better feedback during operations without changing the imported code. Additionally Rockbox Utility and the Theme Editor are now both using QuaZip; currently Rockbox Utility uses a copy of the sources, merging them later is planned. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29645 a1c6a512-1295-4272-9138-f99709370657
