Merge "[Genlist] Add _elm_genlist_item_odd_even_update. elm_genlist now use edje signal for even/odd state. NOTE: if you want to implement even/odd in your theme you know need to listen to both signal : elm,state,odd from elm / elm,state,even from elm. If you set data of stacking_even to above of you item group it will raise the even object above the odd one (that's the default behaviour). You could also explicitly active/deactivate the stacking by setting data of stacking to no. Default is yes."
