Title: Added feature "has_and_belongs_to_many"

if someone defines a model Artists with has_many Categories
and a Model Categories with has_many Artists
one may assume that a 'has_and_belongs_to_many' relation is needed.

I added this feature by syncing the related instances after saving one
of it.
