Preload history into discussion windows (à la mcabber)

- New option load_log defaulting to 200 to indicate the number of lines
  to be loaded
- It’s still very raw, and the format of the message does not match the
  format of the normal room history, for example
- Works in the Private chat, MUC, and Conversation tabs

Thanks to labedz <github@labedz.org> for the original code
