[hibernate-dev] Another @Access quandry

[Steve Ebersole]

To wrap up for now... I went ahead an implemented the strategies we
discussed here.  They are represented as:
1) org.hibernate.metamodel.spi.StandardPersistentAttributeMemberResolver
2) org.hibernate.metamodel.spi.LenientPersistentAttributeMemberResolver

StandardPersistentAttributeMemberResolver implements the JPA spec
guidelines as closely as possible.
 LenientPersistentAttributeMemberResolver tries to be more lenient in the
way Sanne mentioned above.  They will be pushed to master shortly if y'all
wanted to take a look.

Yes, MemberDescriptor and JavaTypeDescriptor are the reflite contracts
