accept any case of boolean strings

  * previously the str2bool function did not accept 'TRUE' as a bool
    type.  This causes the function to now accept TRUE, FALSE strings
    as a boolean type in order to be converted to a proper boolean.
  * This would also cause Y,N, YES, NO to be accepted as boolean types
    as well.
