corrected how when checks if the callback is accepted for the notifier... which led me to the infite loop caused by circular observation... which sucked... corrected this by filtering out propagation from an observable to an observer when this observable is also observer from its observer. This only works on one level.
made the loading of the background queue extensions independent of constants, and more explicit. One needs now to set the queue, and after that, everything else gets included
made the extensions more direct and independent of modules (overwriting wasn't working very well, with aliasing would have worked, lets keep this as an improvement). also grouped the queue options together
added options to the rails configuration, so one can set stuff in the initialization process
Added updated readme
