Update to 1.12b:

--------------
Version 1.12b:
--------------

  - Made an improvement to dictionary generation to avoid runs of identical
    bytes.

  - Added havoc cycle scaling to help with slow binaries in -d mode. Based on
    a thread with Sami Liedes.

  - Added AFL_SYNC_FIRST for afl-fuzz. This is useful for those who obsess
    over stats, no special purpose otherwise.

  - Switched to more robust box drawing codes, suggested by Jakub Wilk.

  - Created faster 64-bit variants of several critical-path bitmap functions
    (sorry, no difference on 32 bits).

  - Fixed moar typos, as reported by Jakub Wilk.

--------------
Version 1.11b:
--------------

  - Added a bit more info about dictionary strategies to the status screen.

--------------
Version 1.10b:
--------------

  - Revised the dictionary behavior to use insertion and overwrite in
    deterministic steps, rather than just the latter. This improves coverage
    with SQL and the like.

  - Added a mention of "*" in status_screen.txt, as suggested by Jakub \ 
Wilk.
