Hi

I did the updates but i still cannot get fontawesome to work unfortunately. It appears it is when swapping out the skin.json lines it breaks but of course that might be related to something else entirely.

@knutmeyn
If you want, I can take a look at it.

Thanks Tealk, I'd appreciate that but the server is behind a firewall still.
Could the issue somehow be related to the server setup?

The impression is that, when/if doing changes stepwise, the fontawesome files still does not appear to be loaded. But that's just my 2cents :)

it's very hard to say anything about when you can't see it
I'd have to take a look at it with the deverlopment tool

Some might be my fault, I just updated the README.md. How are you installing the develop branch version? Since this PR is merged, let's take this conversation back to #47 or #53
