Custom Persistence Handlers should be bean refs for overriding

[phillipuniverse]

Rather than defining custom persistence handlers like this:

    <bean id="blCustomPersistenceHandlers" class="org.springframework.beans.factory.config.ListFactoryBean" scope="prototype">
        <property name="sourceList">
            <list>
                <bean class="org.broadleafcommerce.admin.server.service.handler.CategoryCustomPersistenceHandler"/>
                <bean class="org.broadleafcommerce.admin.server.service.handler.CustomerPasswordCustomPersistenceHandler"/>                
               ...
            </list>
        </property>
    </bean>

It should instead be defined like this:

    <bean id="blCustomPersistenceHandlers" class="org.springframework.beans.factory.config.ListFactoryBean" scope="prototype">
        <property name="sourceList">
            <list>
                <ref bean="blCategoryCustomPersistenceHandler" />
                <ref bean="blCustomerPasswordCustomPersistenceHandler" />
               ...
            </list>
        </property>
    </bean>

This way, someone can override it with their own by just adding:

<bean id="blCategoryCustomPersistenceHandler" class="com.mycompany.admin.service.handler.MyCategoryCPH" />
