Fixed input value conversion bug in EntityNotionProperty and CollectionNotionProperty, added JointProperty
to allow getting and setting several notion-transformed related properties using a single string expression,
e.g. "01.01.2014" to set "day" to 1, "month" to 1 and "year" to 2014. Fixed bug in cardinality enforcement
code of relationship endpoints dealing with dynamic types.
