Make MMS more asynchronous and consistent with new SMS types. 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.

Resolved a few MMS issues. 1) Fixed the "Unsupported Encoding!" problem. 2) Workaround for the Sprint issue, where the MMSC is adding a single extra byte to the end of each encrypted message. 3) Fixed the "large blob of base64 text" on encrypted MMS problem.

MMS and Group Messaging Improvements 1) Display the individual sender name in a group conversation. 2) Add an "address" column to MmsDatabase and keep FROM there. 3) Remove all blocking operations from MmsDatabase.Reader path. 4) Strip SMIL and other undisplayable parts from part count. 5) Fix places where messages weren't being correctly decrypted.
