Title: Changes source to https://rubygems.org.

Using `source :rubygems` will nowadays throw a warning:

```
The source :rubygems is deprecated because HTTP requests are insecure.
Please change your source to 'https://rubygems.org' if possible, or
'http://rubygems.org' if not.
```

This should get rid of it.
