Title:
  set_config() writes to the database even if it's not necessary

Status in Mahara:
  Fix Committed

Bug description:
  Mahara's set_config() methods updates the database every single time
  you call it, even if you haven't actually changed the value of the
  field.

  It would be more efficient if it did not do this. Especially since it
  already does a SELECT statement to check whether it needs to do an
  UPDATE or INSERT, it would be trivial to also make it check to see if
  the value in the database is the same as the value passed by the user,
  and skip that UPDATE if so.
