Message Logger: restore deep in long chats, media through the master, photo fixes

- Deleted messages within the loaded part of a long chat are placed by the
  app among the others (not only at the chat's end), without counting as
  unread; restores no longer repeat every second.
- Logger copies and their media are read through a member of the log group
  signed in here (this account, else the master); the shared file cache
  lets the current account show them.
- Logged chat photos: asked for once per 10 minutes, all sizes downloaded
  (no waits on inline thumbnails), added once the photo viewer closed.
