Add support for using the Scala mutable collection types of Buffer, Set and Map instead of the Java types of List, Set and Map.

package test.s.m

import javax.persistence._
import com.avaje.ebean._
import scala.reflect._ 
import scala.collection.mutable._

 /** 
  * Customer entity bean. 
  */  
 @Entity  
 @Table(name="o_customer")  
 class SCustomer {  
   
   @Id   
   var id:Option[Int] = None;  
       
   var name:String = null;
   
   var smallnote:Option[String] = None;
      
   @OneToMany(mappedBy="customer")
   @JoinColumn(name="customer_id")
   var contacts:Buffer[SContact] = null;

 }

 object SCustomer extends SDao(classOf[SCustomer]) {
                               
 }

Note:

var contacts:Buffer[SContact] = null;

The contacts type is a scala mutable Buffer rather than a java list.
