Title: Allow markdown in crate docs.

This makes the `in-header`, `markdown-before-content`, and `markdown-after-content` options available to `rustdoc` when generating documentation for any crate.

Before, these options were only available when creating documentation *from* markdown. Now, they are available when generating documentation from source.

This also updates the `rustdoc -h` output to reflect these changes. It does not update the `man rustdoc` page.
