So, for some reason, "public.rtf" isn't defined when running in the simulator, but it is when running on the device. I don't know if I just didn't notice this before, or if it changed at some point (probably the former).

Anyway, I've added public.rtf in our Info.plist's UTImportedTypeDeclarations. This lets our definition get used if there isn't one exported by someone else (on the simulator) or do nothing if there is one (on the device).

In order to get this change to show up, I had to blow away my iPhone simulator state (removed ~/Library/Application\ Support/iPhone\ Simulator) and Xcode build output, else the simulator's cache of UTI information didn't get rebuilt properly.
