function domain_form_alter in Domain Access 7.2

Same name and namespace in other branches
5 domain.module \domain_form_alter()
6.2 domain.module \domain_form_alter()
7.3 domain.module \domain_form_alter()
This function is crucial, as it appends our node access elements to the node edit form. For users without the "set domain access" permission, this happens silently.
