Subject: [PATCH] Partial implementation for Issue 1059.  Doesn't help those
 without physical keyboards, though, and should be modified to only re-setup
 pushers.  Current implementation causes a wasteful reschedule of polling.

Also gets the help Toast for the folder up-to-date after the
FolderList/MessageList split.
