update: Better formatting for sticky notes
update: Better formatting for sticky notes

* Added better formatting for sticky notes via format_note function that
  makes sure that the user who is supposed to receive the note is
  addressed in the message that is being sent.

* Also redone the way the notes are being iterated through so that all
  those which have been already sent would not appear anymore.
