Add a list of third-party layouts for floppyforms to the documentation

[gregmuellegger]

There are packages that implement layouts for floppyforms, it would be good to either include those in the documentation or have a seperate grid on djangopackages.com

Example: https://github.com/grundleborg/django-floppyforms-bootstrap3

Hello, I did a post regarding the django-floppyforms and how it help me in the integration with frontend team, I'd like to see if this is helpful, in this case perhaps, we could find out some where in the documentation to link to it.
