Enhance usb-storage

Make it possible to define more than just one usb storage and store them
to the new QSettings item "paths/usball", a QStringList while
repurposing the old setting "paths/usb" for writing.

When reading, iterate over all entries in usball until the file is
found. For writing, or moving files to archive, use paths/usb as target.
