docs: Get the last status message if it is at this level or above.
  Typically you do this to see if the current message you want to display can
  be displayed on top of the message that is there already.
  Calling this method will clear the last status text.
  @param iWarningLevel The maximum warning level to retrieve.
  @return The current message if at this level or above, otherwise return null.
