Github Pages metadata clashes with config file

[theholy7]

Having:

github:
    repo: "<repo_url>"

in the _config.yml file prevents the page from building successfully.

Also the theme is not correctly using (or doesn't allow the user to select) the Github Pages Metadata.

For example, in the sidebar HTML file, we have site.github.repo rather than site.github.repository_url.

I can confirm the first issue. If site.github.repo is set in _config.yml, then github-pages (using the remote_theme functionality) refuses to build the site and gives the following error message:

Your site is having problems building: The hydeout theme is not currently supported on GitHub Pages

However, simply removing these lines resolves the issue.

This should be fixed in master and v4.0.0 of the gem. The github config in master is gone, and the _config in the gh-pages branch now uses a hydeout.repo instead.
