ReStructuredText Youtube / Vimeo video embed directive

# -*- coding: utf-8 -*-
"""
    ReST directive for embedding Youtube and Vimeo videos.

    There are two directives added: ``youtube`` and ``vimeo``. The only
    argument is the video id of the video to include.

    Both directives have three optional arguments: ``height``, ``width``
    and ``align``. Default height is 281 and default width is 500.

    Example::

        .. youtube:: anwy2MPT5RE
            :height: 315
            :width: 560
            :align: left

@jukent hehe, nice that this is still being used 🙂

Alignment options are left, center and right. I don't know if it still works, you may need to adjust the code. I haven't used this in a long time.

Suggest to update the iframe embed url from http to https, otherwise this error may pop up
