convert: add config option to use the local time zone

The default for the time zone offset in a converted changeset has
always been 0 (UTC).  With this patch, the converted changeset is
modified so that the local offset from UTC is specified as the time
zone offset.

The option is specified as the boolean convert.localtimezone (default
False).  Example usage:

    hg convert -s cvs --config convert.localtimezone=True example-cvs example-hg

IMPORTANT: the patch only applies to conversions from cvs or svn.
The documentation for the option only appears in those two sections
in the convert help text.
