Title: Update the documentation for the :autosave option on belongs_to

I've noticed a caveat with the :autosave option biting people before.
Questions arise about why they must explicitly save an associated object
in their own before_save callbacks. I've updated the documentation as
such to note to users that the :autosave callback occurs before any
user defined callbacks. They must save the associated record themselves
if altering it in their own callbacks.
