docs: optimize head section of templates Reordered the head section of website/www using capo.js to improve speed. Tried to do the same for the doc/_template/layout.html. Due to a bug in sphinx, we get duplicate viewport tags. https://github.com/sphinx-doc/sphinx/issues/11699 but I think it's harmless.

from roundup.dist.command.build import build_message_files, check_manifest
from setuptools.command.install_lib import install_lib as base

class install_lib(base):

    def run(self):
        check_manifest()
        build_message_files(self)
        base.run(self)
