  Modified files:              
    /loncom/interface	lonnavmaps.pm 
  Log:
  * Added alt tags to the status icons for accessibility.
  * Handled "ungraded_attempted" status.
          * If the problem is untried, it shows "open" as usual.
          * If the problem is tried and ungraded, no status icon is
            shown and the text "Not yet graded" shows in the last col.
          # If the problem has been graded, the status of the problem shows
            as it usually does for correct & incorrect.
  * Fixed two "ROWS" -> "COLS". (Duh.)
  * Corrected (?) status message display to get the composite status.
  * Corrected some comments.
  * Found a subtle dependency on parts having numeric names: != used
    instead of 'ne'. D'oh! That's why Guy's problem wasn't working 
    right.
