HBX-2390: Create a JBoss Tools adaptation layer in Hibernate Tools

[koentsje]

• Change class 'org.hibernate.tool.orm.jbt.wrp.TableWrapper' into an interface
• Create new class 'org.hibernate.tool.orm.jbt.wrp.DelegatingTableWrapperImpl' that extends Table and implements TableWrapper
• Modify methods in class 'org.hibernate.tool.orm.jbt.wrp.DelegatingPersistentClassWrapperImpl' to wrap the result
  • DelegatingPersistentClassWrapperImpl#getRootClass()
  • DelegatingPersistentClassWrapperImpl#getTable()
• Handle the 'getAssociatedClass()' case in 'org.hibernate.tool.orm.jbt.wrp.ValueWrapperFactory.ValueWrapperInvocationHandler' to wrap the resulting PersistentClass instance
• Modify method 'org.hibernate.tool.orm.jbt.wrp.createTableWrapper(String)' to create an instance of DelegatingTableWrapperImpl
• Rename class 'org.hibernate.tool.orm.jbt.wrp.TableWrapperTest' into 'org.hibernate.tool.orm.jbt.wrp.DelegatingTableWrapperImpl' and adapt to the new implementation
• Add some methods to class 'org.hibernate.tool.ide.completion.HQLCompletionProposal
  • aliasRefKind()
  • entityNameKind() * propertyKind() * keywordKind() * functionKind()
