font.js is written in a non-strict mode

Uncaught ReferenceError: assignment to undeclared variable WebFontConfig is being raised when importing the assets using the rails importmap with an old version (1.5.2). The fix is fairly simple - var needs to be added in front of the WebFontConfig in the fonts.js

I would open a PR, but there is no branch for the 1.5.2 :)

@jan-bw I just created a v1 branch. You can create a PR against that.

Also, I've switched to using importmap-rails in my app too, but I've yet to switch AA assets. I want to get good support for it in here. That will probably be a v3 thing, because it will involve switching back to a gem, I think.
