These commits add better support for generating and serving files with custom or no filename extensions.

The tagger plugin can now generate archives without any filename extension if it is set to `null` in `site.yaml`:

    tagger:
        archives:
            all:
                extension:
                target: t
                …

The `hyde serve` command has a new argument to modify the MIME type extensions map. Example:

    hyde serve -t text/html -t text/plain .srt .asc -t application/x-xz .xz

This sets the default MIME type to `text/html` (rather than `application/octet-stream`) and maps `.srt` and `.asc` to `text/plain` and `.xz` to `application/x-xz`.

Currently if
<pre>
urlcleaner:
  strip_extensions:
    - html
</pre>
options is given, hyde.server will fail to serve stripped urls, which is very inconvenient.

This allow to handle media_url to external site (like
http://media.example.com).

This is a simple publisher that uploads a zipfile to PyPI.  I am starting to do some basic websites for my python modules using Hyde and hosting them on packages.python.org.

Like optipng.

Maybe we could put all those image related plugins into the same module?
