bot checks for http://www.github.com now

I tried posting some stuff on r/coolgithubprojects, but my link was rejected. Kind of annoying, but it said you open sourced the tools behind it, had a quick peek of the source code and found that http://www.github.com wasn't being checked, so unless you use https://www... it wont work! I don't write Python, but hopefuly this works. I also cleaned up the url code so it's a bit more readable.
