In webservices / csv upload we deal with the variable 'submitpages' in
relation to if one can submit pages to group. But the group
create/update functions and db table expect 'submittableto'.

The csv upload function converts this as expected but the webservices
didn't.

Have made adjustemets to webservices to suit
