[Hibernate] support for ON CASCADE DELETE

[Gavin King]

I've implemented support for ON DELETE CASCADE foreign key
definitions for parent/child associations (ie. for inverse
one-to-many).

You map this like:

<set name="children" inverse="true" cascade="all">
   <key name="PARENT_ID" on-delete="cascade"/>
   <one-to-many class="Child"/>
</set>

So, when the Parent instance is deleted, Hibernate
does not need to perform n+1 deletes; instead, we
leave that to the database to take care of.

Any comments?
