The "egg_info" command now always sets the distribution metadata to "safe"

forms of the distribution name and version, so that distribution files will
be generated with parseable names (i.e., ones that don't include '-' in the
name or version).  Also, this means that if you use the various ``--tag``
options of "egg_info", any distributions generated will use the tags in the
version, not just egg distributions.
