Subject: [PATCH] Only let browser search through source code until it's
 expanded (#1181)

Something that's been bothering me is that while the source code is
not visible by default, the browser still jump to it when searching.
Adding the `visible` property prevents this.

Test it out yourself:
* `bundle exec rdoc`
* open `_site/index.html`
* Search for `NameError`

Before, you will get a match from `load_yaml` source code, after
you only get the match when that methods source code is expanded.
