hgweb: generate archive links in order

It would be nice for archive links to always be in a certain commonly used
order, such as 'zip', 'bz', 'gzip2'. Repo index page (hgwebdir_mod) already
shows archive links in this order, let's do the same in hgweb_mod.

Sadly, archivespecs is a regular unordered dict, and collections.OrderedDict is
new in 2.7. But requestcontext.archives is a tuple of archive types, so it can
be used as an index to archivespecs.
