Parameterise BeanstalkProcessor and RedisProcessor by their delivery target classes
Move Beanstalk/Redis processors into a separate package
Move service activator and provider service into a services package
Refactor RawBeanstalkModule as the type parameter to BeanstalkProcessor now distinguishes tube handlers
Move spooled event processor etc into packages and import tests
Allow binding annotation to be passed to SpooledQueueModule
Refactor how spooled queue processors are wired, still ugly though
SpooledQueueProvider implements ProviderWithDependencies
