[orchestra] changed scope configuration

[Mario Ivankovits]

Hi!

Today we cleaned up the way how to configure the different scopes.

Basically this means:
* you HAVE to configure a timeout now. The default is to never timeout a
conversation on its own.
* the flash scope is now configured through the "lifetime" property.

Please see here an example or refer to the updated installation
documentation (once it has been published which might take some hours)

                <entry key="conversation.normal">
                    <bean
class="org.apache.myfaces.orchestra.conversation.spring.SpringConversationScope">
                        <property name="timeout" value="35" />

                        <property name="advices">
                            <list>
                                <ref
bean="persistentContextConversationInterceptor"/>
                            </list>
                        </property>
                    </bean>
                </entry>
                <entry key="conversation.flash">
                    <bean
class="org.apache.myfaces.orchestra.conversation.spring.SpringConversationScope">
                        <property name="advices">
                            <list>
                                <ref
bean="persistentContextConversationInterceptor"/>
                            </list>
                        </property>
                        <property name="lifetime" value="flash"/>
                    </bean>
                </entry>
