Error while applying Disqus. [has solution]

[quark325]

I had a problem with applying Disqus for the past few days, and finally, find out the issue.

Currently, the _config.yml template does not have 'baseurl' and 'url' properties. If they are not set, Disqus cannot be used smoothly even if disqus_shortname is set.

The error message is: 'We were unable to load Disqus. If you are a moderator please see our troubleshooting guide.'

So how about adding documentation about explaining it? I solved this issue by looking
#48 and jomei's repository. I could make a pull request to add documentation about this issue, but it seems so little to make a pull request about it, I made an issue.

Env: I used your Jekyll by cloning your repository.

Thanks for reporting the issue @quark325. It would be helpful for others if you could make a PR and add the docs in the disqus section of the README.
