Give Hibernate rule hints more concise titles

From Marc:

• Rules having a long and non-title tilte name like "Replace class org.hibernate.jdbc.Batcher and its implementations" should be renamed to be able to relate it directly to the real issue more directly, for example using a common naming suffix "Hibernate 4", as in the rules in my PR. This means for example...
  "Replace class org.hibernate.jdbc.Batcher and its implementations" -> "Hibernate 4 Batcher replacement"
  "Replace class org.hibernate.jdbc.BatcherFactory and its implementations" -> "Hibernate 4 BatcherFactory replacement"
  "Replace class org.hibernate.engine.SessionImplementor" -> "Hibernate 4 SessionImplementor replacement"
  "The removed classes in org.hibernate.classic package " -> "Hibernate 4 Deprecated classes"
  I am sure that other rules like that should be reviewed.

I think the naming suggested is not quite correct – they imply that we're replacing the Hibernate 4 version of something with a newer version, but these are rules are for moving TO Hibernate 4.

I'd suggest wording like:
BatcherFactory deprecated in Hibernate 4

and for the last one about org.hibernate.classic:
org.hibernate.classic removed in Hibernate 4

If we do remove the FQCNs from the titles, this applies to the Hibernate 4->5 rules too.
