[Feature Request] Right-justified Text for right-justified header/footer

[mermelmadness]

There should be a header-right and footer-right that right-justifies the text, too.

This is easily accomplished via the card mod:

    card_mod:
      class: middle-right
      style: |
        ha-card {
          text-align: right;
        }

Thanks @smugleafdev. I think I like that solution instead of introducing another several sets classes.
