Moxie Marlinspike 3a8d29e279 Major reorganization of view/model interactions.
Mostly, the inheritance graph for MessageRecord/MmsMessageRecord was
all messed up, and each class was overloaded for things it shouldn't
have been.

1) Broke MessageRecord/MmsMessageRecord up into: DisplayRecord, ThreadRecord,
MessageRecord, SmsMessageRecord, NotificationMmsMessageRecord, and
MediaMmsMessageRecord.

2) Updated all the adapters/views to keep pace with that change.
