title: Generate "on delete cascade" using Ebean
body: <p>I am using Ebean and I need to end up getting "on delete cascade" as DDL (data definition language) - which annotation does that? I tried </p>
  
  <pre><code>@OneToMany(cascade=CascadeType.REMOVE)
  </code></pre>
  
  <p>but that gives "on delete restrict" / doesn't change the default "on delete restrict"?</p>
