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.
