Subject: [PATCH] Never get downloads from the cache.

This is a workaround for corrupted files because Qt somehow reads them from the
cache wrongly. See https://bugreports.qt-project.org/browse/QTBUG-42757

This might fix a part of #78 - but we'll leave this open for now, since it
might also be another issue.
