hgweb: fix dynamic date calculation not working under Safari

While Chrome, Firefox, and IE 6+ support the current date format being
passed to Date(), Safari doesn't:

> new Date('Mon Oct 24 13:58:01 2011 +0200')
  Invalid Date

However, the rfc822date format--officially supported by
ECMAScript[1]--does work:

> new Date('Mon, 24 Oct 2011 13:58:01 +0200')
  Mon Oct 24 2011 04:58:01 GMT-0700 (PDT)

This change replaces all instances of {date|date} in HTML with
{date|rfc822date}. For elements that only have the "age" class,
there's no outward change for users with JavaScript enabled. For
elements with both the "age" and "date" classes, the full date
displayed uses the new format.

Tested in IE 6, Safari 5.1.1, Google Chrome 15, and Firefox 7.0.1.

revlog.parseindex must be able to parse the index file even if
an index entry is split between two 64k blocks.  The ideal test
would be to create an index file with inline data where
64k < size < 64k + 64 (64k is the size of the read buffer, 64 is
the size of an index entry) and with an index entry starting right
before the 64k block boundary, and try to read it.
We approximate that by reducing the read buffer to 1 byte.

  $ cd a

  $ hg commit -m 'add foo'
  $ echo >> foo
  $ hg commit -m 'change foo'
