Upstreaming new hubs patterns into fedora-bootstrap

[Máirín Duffy]

Hi,

As we discussed in the hubs status meeting yesterday, I've put together
a PR for fedora-bootstrap to upstream the new hubs patterns Eric and I
worked on this summer.

This is necessary as part of removing the patternlab CSS from fedora-hubs.

Here is the PR:
https://pagure.io/fedora-bootstrap/pull-request/9

Once this is merged into fedora-bootstrap upstream, we'll need to pull
down a new version of fedora-bootstrap.

I am worried about how upstreaming into fedora-bootstrap is going to
slow things down, but ultimately I think it's the best way to add new
styles for fedora-hubs to use.

Cheers,
