Release 1.2

Added Consumer Hook

• now can register ConsumerHook function that will be run while firing up the consumer routines and that return value will be set/passed to each job. This is particularity useful when creating a saving pool so a the consumer hook would create a database connection for each job to reuse instead of creating an additional one for each job.
