New Tooling

API changes

• Removed duplicate getter getMessageHistory on ManagedCamelContextMBean

• Added org.apache.camel.spi.SynchronizationRouteAware

• Added beforeRoute and afterRoute methods to UnitOfWork.

...

• Polling Consumer allows to configure initial queue size and whether to block when full when using the default EventDrivenPollingConsumer which most components does. We now block by default, as otherwise the message may be lost if the queue was full, and a new message was offered.
• camel-scala upgraded from Scala 2.10.x to 2.11.x
• The option useSsl has been removed from camel-twitter as ssl is always enabled now, enforced by twitter
• Fixed Restlet to return error code 405 (instead of 404 if a http method is not allowed
• Routes starting from JMS will now shutdown the consumer (MessageListenerContainer) quicker when CamelContext is being stopped. (assuming the acceptMessagesWhileStopping hasn't been set to true). This can also help a cleaner shutdown as otherwise some JMS clients may attempt re-connect/failover during shutdown which isn't desired anyway as we are shutting down. If you want the routes to keep accepting messages during shutdown of Camel, then set acceptMessagesWhileStopping=true.
• OnCompletion now runs without thread pool by default. To restore old behavior set paralllelProcessing to true.
  
• Setting autoStartup to false, and starting a CamelContext the 2nd time now does not start the routes, instead use the new startAllRoutes method on CamelContext to start all the routes.
