Update URL for 2000/84/EC directive governing current EU DST

[Colin Watson]

The 'europe' file in tzdata-2009i has this link:

  # The most recent directive covers the years starting in 2002.  See:
  # <a href="http://europa.eu.int/eur-lex/en/lif/dat/2000/en_300L0084.html">
  # Directive 2000/84/EC of the European Parliament and of the Council
  # of 19 January 2001 on summer-time arrangements.
  # </a>

The URL given there no longer works properly. Here's an updated one,
which Ian Jackson found by way of a search engine:

  http://eur-lex.europa.eu/smartapi/cgi/sga_doc?smartapi!celexapi!prod!CELEXnumdoc&lg=EN&numdoc=32000L0084&model=guichett

Thanks,
