Recipe-scrapers

Bugfix release:
* foodandwine: implement 'yield' field support (881)

Thanks jknndy!

Fixup; the 14.49.2 release failed due to a validation error on the `long_description` field on the Python package (two reStructuredText hyperlinks both named `here`).

Adds support for:

- grouprecipes.com (873)
- norecipes.com (871)

And adds ingredient group functionality to:

- Add A Pinch
- Allt om Mat
- Alton Brown
- Amazing Ribs

... courtesy of pull request 874.

Thanks again, jknndy!

A smorgasbord of additional scrapers thanks to jknndy as is standard recently :)

- plowingthroughlife.com (863)
- onceuponachef.com (864)
- tidymom.net (865)
- themagicalslowcooker.com (867)
- fattoincasadabenedetta.it (868)
- waitrose.com (869)
- eatwell101.com (866)
