Bulk closing tickets resolved in released versions

Introduced the concept of ConfiguredClass, ConfiguredClassHierarchy and MappedAttribute. These classes serve as "middle man" between the configuration defined via annotations and the Hibernate metamodel. The framework is in place, but will needs extension as we go

Before we can create the Hibernate metamodel classes we need to pre-process the annotated classes to determine things like the default access type, inheritance type, etc. We also need to resolve generic parameters for embedded types and mapped superclasses.
Introducing an additional layer between annotations and the metamodel distributes the parsing/binding code more. Otherwise the binder classes would be very heavy weight.
