Change tracing from qDebug() to use cutelogger, which is available under the
LGPL2.1. This allows to automatically add filename and line number to the log,
and also provides multiple log levels.

Give the user a chance to cancel the backup if the selected file already
exists. Since the filename is automatically generated from the installation
version information this can happen when trying to create a second backup of
the installation.

The "Installation" dialog allows backing up the current installation by
creating a zip file from the .rockbox folder since quite a while. However, this
has the drawback that you need to update your build to create a backup, but
creating a backup might be desireable in other cases as well (before updating
themes, or just for backup reasons). Since the functionality is somewhat hidden
it's also not obvious to users such a functionality exists (most users are
likely to use the "Quick Start" instead).
Implement backup functionality as dedicated dialog placed on the Uninstall tab.
Rename the Uninstall tab to accommodate this.
