error.LookupError: rename 'message' property to something else

At least some installs of Python 2.6+ complain with:

    mercurial/error.py:26: DeprecationWarning: BaseException.message has been
        deprecated as of Python 2.6

This patch renames the property away from 'message' so that Python no longer
complains.
