Allow user to be set in url on gh-pages

[kirkins]

I often found I wanted to look through my history using this but would search every-time.

I wanted to be able to do something like this:

https://kirkins.github.io/github-activity/?user=kirkins

So I figured I'd send a pull request. Though I realize this may just be adding an unneeded feature to something meant to be an mvp.

Best, Philip

P.S. I'm only changing the gh-pages branch not modifying the base library like the other open pull-request.

Just a suggestion, you could use:

var parsedUrl = new URL(window.location.href);

var username = parsedUrl.searchParams.get('url');

And then use if statements to put in the default

PS: https://github.com/colmdoyle/gh-activity supports this: https://cdoyle.me/gh-activity/gh-activity.html?user=ypid&type=user :)

I like this idea a lot. I think it could be implemented a little more cleanly using @turquoise-turtle's solution.
