Title: added :callbacks => false functionality for create, save, update_attribute(s)

Added the option of :callbacks => false to create, create!, save, save!, update_attribute, update_attributes, and destroy.

This will allow anyone to easily disable the before/after create/save/update/destroy callbacks.
