    Change underscores to hyphens for labels

    * lisp/org-exp.el (org-export-define-heading-targets): Currently,
    the section number (a string of the form "X.Y.Z") is used to
    manufacture a section label of the form sec-X_Y_Z. Underscores are
    overloaded however, both in org and in LaTeX, and cause conflicts
    with some packages. This patch changes underscores to hyphens in
    section labels.

    TINYCHANGE

    Peter Frings reported a conflict with the ``syntax'' LaTeX
    package. Light testing (exporting simple files to LaTeX, by both
    Peter and myself, as well as exporting to ascii and HTML) has not
    uncovered any problems. I have not tested docbook, or Jambunathan
    K's odt exporter.
