Set username from query string parameter user if present

This allows links like https://domain/path/to/index/?user=moparisthebest to work without any server side scripting language, example:

https://www.moparcraft.net/skins/?user=moparisthebest

I also changed http: to // for fonts.googleapis.com so it will work regardless of protocol.

Only concern is that Array.prototype.forEach doesn't exist in IE8 - but also - who cares about IE8?

It could be implemented without that as well, does this even run in IE8? :)

It used to run in IE9, not sure if it still does.
Surprisingly, this viewer runs a lot better in IE11 than Chrome on my work computer.

If there's a solution that covers more browsers, I might as well use that solution instead, provided it's not too convoluted.
I wonder if http://stackoverflow.com/questions/11582512/how-to-get-url-parameters-with-javascript/11582513#11582513 is IE8 compatible?
