Add fuux library to libraries list

[henriquecustodia]

Hello,
I'm developing a flexbox library based on angular-material style. This library is just to structure any layout, so it hasn't any style.
Can you take a look and maybe add to library list, if it is useful for anyone?

The library is under development, I have to implement many things yet but it is on Alpha version.

Thanks
