Push Notification Ads: JSON

For Push Notification ads the adm parameter should contain a JSON encoded string like this (note that we use the 'native' object to implement push notification ads). Width and height depend on the width and height coming from request. Currently supported dimensions are 192x192 and 720x480. One image asset per notification.
