No CaloCalTopoClusters in HImode

This MR introduces a blacklist of CaloTopoCluster containers which won't be written in ESD and AOD. By default, this list is empty and the behaviour is thus unchanged.
In HImode, it will prevent writing CaloCalTopoClusters (or CaloTopoClusters) and only SubtractedCaloCalTopoClusters (or SubtractedCaloTopoClusters) will be written.

It also slightly modifies HIRecConfig.py, so all the flags in HImode are loaded.
