Cleanup and un-gui ZipInstaller class:
- Use signals for updating the progress logger from ZipInstaller class. - Move ZipInstaller class to base folder as it doesn't rely on QtGui anymore. - cleanup debugging output a bit. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@20845 a1c6a512-1295-4272-9138-f99709370657
