Subject: [PATCH] Fixes. Record handling in separate routes

Fixed some target names. The routing facility of the multi filter is
now used to separate record handling (marc-8 or utf-8).
Side issue: xmllint --format config-loc.xml does not produce nice
indenting for parts of the file .. Seems to be a bug in xmllint/Libxml2.
