fix bug where after removing an item from an eq sub group a message would appear that indicated there were no more items in the sub group even if that was not true - fix was changing an = to an ==; tweaking css for eq group page in listing sub groups and items
NOTE: DB schema update! items now can have images; item editing/adding form supports images; images are appropriately uploaded and associated; images can be removed from items; unrelated- tweak comm pref test to use new layout (checkbox first)
