AccountFolderList, MessageCompose and MailboxList.
Also,
- ControllerResultUiThreadWrapper now takes a Handler instead of an Activity.
So that it can be used from a Service as well.
- ControllerResultUiThreadWrapper.getWrappee() to get the wrapped object.
We'll eventually need this.
- I'll work on MessageList too, but the might be relatively
large, so I'll do that in a separate CL
