* All Tools: 

- New: Added FreeBSD/Ubuntu patches from Otacilio De Araujo
       (<otaciliodearaujo@gmail.com>).

  * ./cumulus:
    - Change: In placeandroute.py, raise ErrorMessages (from crlcore) instead
        of deprecated strings.
    - Change: In pyRouteCk, the clock grid now systematically covers the core
        area instead of only the area where clock signals are useds. This is
        to alleviate the constraint of alignement on the pvsseck pads (they
        must be in direct regard of the clock grid).
