Update FontAwesome to 4.6.1

[zhedar]

As FA 4.6.1 is available now, maybe we should update to that version with 0.8.2?

Doesn't sound risky to me, so you've got my "go!". Do you know what's changed since 4.6.0?

[zhedar]

We're currently running 4.5. Apparently 4.6 added 23 new icons, but something was wrong with 4.6, so 4.6.1 followed in an instant.

I just found out how to upgrade the FA version we use and apparently, we only get it from CDN and don't bundle it locally. It wasn't in a property file, where I looked for it. I will include this small change in my current PR.
If we set the load from CDN context param to false and FA isn't included by another library (e.g. PrimeFaces) or by the user himself we won't load it at all, is that working as intended?

@zhedar can I close this issue?

It will get closed automatically, when #347 get's merged. So if you want to do that, feel free.
