assembled all active record specs into one big block which is tested for all queues, much in the same way we built a block for all ORMs
finally added queuing tests to datamapper
corrected the require of example spec
removed requires of still unsupported delayed job DM handler
removed commented unneeded stuff
updated railtie
updated spec task
corrected stuff to work under 1.8.7 and "silenced" sidekiq for it (unsupported)
