Support for fomantic-ui

[Polve]

It seems like that all new development in semantic-ui is happening in the foomatic-ui repository, so it would be great to have support for that package too, and since it's a fork of semantic it should be relatively easy.

Simple instructions on how to do it by hand would be useful too.

I opened another bug there so I leave here the link for reference: fomantic/Fomantic-UI#745
