1) We now delay MMS notifications until a payload is received, or there's an error downloading the payload. This makes group messages more consistent. 2) All "text" parts of an MMS are combined into a second text record, which is stored in the MMS row directly rather than as a distinct part. This allows for immediate text loading, which means there's no chance a ConversationItem will resize. To do this, we need to include MMS in the big DB migration that's already staged for this application update. It's also an "application-level" migration, because we need the MasterSecret to do it. 3) On conversation display, all image-based parts now have their thumbnails loaded asynchronously. This allows for smooth-scrolling. The thumbnails are also scaled more accurately.
