hgweb: teach archive how to download a specific directory or file

The archive web command now takes into account the "file" request entry, if one
is provided.

The provided "file" is processed as a "path" corresponding to a directory or
file that will be downloaded.

With this change hgweb can to process requests such as:

    http://mercurial.selenic.com/hg/archive/tip.zip/mercurial/templates

This will download all files on the mercurial/templates directory as a zip file.
It is not possible to specify file patterns ('glob', 'relglob', 'path',
'relpath', 're', 'relre' nor 'set'). The server will reject those with a
403 HTTP error response.

Note that this is a first step to add support for downloading directories from
the web interface. A following patch will modify the archiveentry map entry on
the different templates so that it adds the current folder path to the archive
links.
