Subject: [PATCH] Make the bibliography section regexp a bit more robust

The regexp now looks for a blank line to precede the bibliography
<div> section.

Right now the div section is inserted by oc-csl like this:

    ```

    <style>.csl-entry{text-indent: -1.5em; margin-left: 1.5em;}</style><div class="csl-bib-body">
    ```

This updated regex should work in the case that changes to something
like below as well:

    ```

    <style>.csl-entry{text-indent: -1.5em; margin-left: 1.5em;}</style>
    <div class="csl-bib-body">
    ```
