Get rid of warnings

[Zehvogel]

There are still some warnings emitted for every event at the moment, we should fix that.

=================== WARNING ===================
static method CellIDDecoder::setDefaultEncoding
does nothing anymore. Use the constructor to 
specify your encoding string !!
===============================================
[ MESSAGE "MyDDMarlinPandora_10ns"] Failed to extract ecal calo hit collection: ECALOther, lcio::DataNotAvailableException: LCEventImpl::getCollection: collection not in event:ECALOther

• remove ECALOther Remove unused ECALOther collection from digitizer and pandora #14
• find where CellIDDecoder warning comes from and fix it... see e.g. Default encoding steering parameter is obsolete in SimpleFCalDigi iLCSoft/MarlinReco#100

FYI iLCSoft/MarlinReco#129 might fix this.

Another that should fix a few: iLCSoft/DDMarlinPandora#25
