Realthargor/smslib

source for org.opennms.smslib jar is missing, it's only in the onms repo
the reason for an onms release of smslib was a missing feature (USSD)
USSD was fixed in org.smslib 3.4.6 which is not in maven and can't be build
so I upgraded onms to smslib 3.5.x

I don't know howto test it but it's building ...
