Title: Added sortable for has_many

See: https://github.com/gregbell/active_admin/issues/880

This includes the commit from https://github.com/gregbell/active_admin/pull/877 because the test here depends on the unit test setup for the has_many method.

This can still use some front-end treatment, as it's pretty much an invisible feature at the moment.
