Subject: [PATCH] Use Base64-decoder from JAXB instead of Apache/Sun

This removes the dependeny on Apache Commons Codec, which was solely used for Base64 decoding.
Uses of both org.apache.commons.codec.binary.Base64 and sun.misc.BASE64Decoder are replaced by javax.xml.bind.DatatypeConverter which is part of Java since 1.6.
