shipping - fix some datatables
variations - bug fix

The 'add option' button is now disabled when editing a store variation
from within a product (there's no save mechanism for editing global
variations from here).  That save button issue is on the list, but may
require some changes to the variations flow.
Syndication - bug fix

The data returned for a mkt detail has schedule as lowercase but the
template was looking for uppercase.
Additionally, the renderFormat had a bug that was causing the value to
not get selected.
