    PR13546 Cont'd: Updated NEWS

commit 54e2d76c4a0f5a8f1bb9ff31ebc82b29193935cb

    PR13546 Cont'd: Fixed failing test cases
    
    Since we introduced a random seed to the hash function,
    certain tests that printed results in an unordered
    fashion could now fail, since the order is not necessarily
    the same from run to run. These tests have been fixed and now
    print in a certain order as to avoid those errors.

commit f99a86ea97ab942378d72d696bd5a07b51ba8a51

    PR13546 - Improve Map Hashing
    
    - Made str_hash() in map.c more hashy.
    - Introduced a runtime random seed to the hash calculations
      to reduce the chance of deliberate hash collision inducing
      attacks.
    - Made the HASH_TABLE_SIZE depend on MAXMAPENTRIES, rather than
      just a static 256. This effectivly increases the size of the
      hash table.
