export: show 'Date' header in a format that also is readable for humans 'export' is the official export format and used by patchbomb, but it would only show date as a timestamp that most humans might find it hard to relate to. It would be very convenient when reviewing a patch to be able to see what timestamp the patch will end up with. Mercurial has always used util.parsedate for parsing these headers. It can handle 'all' date formats, so we could just as well use a readable one. 'export' will now use the format used by 'log' - which is the format described as 'Unix date format' in the templating help. We assume that all parsers of '# HG changeset patch'es can handle that.

factotum: fix urllib2 import so it no longer relies on a demandimport bug demandimport will do that urllib2 can be imported 'from mercurial' even though it doesn't exist there.

hgweb: make the test suite use hgweb in a more WSGI compliant way - as checked by wsgiref.validate. This makes sure that we don't optimize hgweb for invalid use cases.
