EDIT

better use of generics in service layer and persistence list methods

adapt the service method loadChildNodesOfTaxonNode
with param recursive choose whether you get only the children of the node or the children of the children ...

remove imports and javadoc

Changed limits to INTEGER, so it is possible to nullify these parameters if needed

*added Test for service method: getTaxonOfAcceptedTaxaByClassification and countTaxonOfAcceptedTaxaByClassification
*fixed SQL Statement so it works with H2 DB

TestDatabase / CdmPersistentDataSourceTest / CdmApplicationUtils : updated as per Cdm Source refactoring
ICdmDataSource : moved generic methods to super interface ICdmSource
CdmPersistentDataSource : refactored by spliting the utility part to CdmPersistentXMLUtils and the jDom elementpart to CdmXMLPersistentSource...

performance improvement for listChildNodes of a taxon

adating test to modified number of taxa

implementing dao method listAcceptedTaxaFor, for #4112

add NomStatus vocabulary for ICZN #4085
