Integrate font-awesome icons

[tabascoeye]

The footer is very nice with all our accounts on all social media etc.
But it needs more visibility.

I suggest we incorporate fontawesome: http://fontawesome.io/icons/

by inserting
<link href="//maxcdn.bootstrapcdn.com/font-awesome/4.1.0/css/font-awesome.min.css" rel="stylesheet">

and then we can use e.g.:
<li><a href="https://twitter.com/raumzeitlabor" data-category="Footer" data-event="Footer: Twitter"><i class="fa fa-twitter"></i> Twitter</a></li>

I'm not sure if that's already included in bootstrap. I assume it is something else than the glyphicons?

I agree we should have awesome icons. Integration should be easily doable with bower.

It is something else we should use it :D

Glyphicons are only stripped for bootstrap and they have really shitty licenses stuff for the social media icons...

shouldn't we update all of our foo?

No objections as long as it does not break anything. We will not be able to keep up with the libs' development pace though.
