region => target mapping doesn't work when field_group and nodeformcols installed

So at some point after 7.x-4.0-rc1, it looks like there was code added to rubik_preprocess_form_node() that allows field groups (group_sidebar, group_footer) to move fields into different parts of the page (similar to nodeformcols does).

Unfortunately, if you have both modules installed, the nodeformcols mapping doesn't happen and you end up with a messed up node edit form.

I think it would work well if the mapping tables worked together if both modules are installed. I haven't tested how things would work if you tried to use both the group_sidebar/group_footer and nodeformcols together. My patch does allow for nodeformcols to work properly with regular field groups (not mapped).
