* now it is possible to have a showrtcut for a sub attributes (i.e. calling it directly with enum name, e.g. type -> type.key) with directly specifying the defaultSubEntityAttribute
* no need to have single sub attribute in order to have a default sub attribute
* added TYPE search field for TargetFields (sinonim of targettype)
* targettype is deprecated - to be decided if and when to be removed
* returned back "type" direct search (with meaning type.key) for DistributionSet and SoftwareModule as non-depricated
* add serche with "type" as type.key for Target
