Asanka Herath c9e679075f Add configuration options for pandoc
Current options are:

  markup:
    pandoc:
      filters:
        - list
        - of
        - filters
      extensions:
        - list
        - of
        - extensions
      extraArgs:
        - --extra-arguments
        - --one-per-line

Generalize some Pandoc options.

Support configuring a bibliography in markup config

Anonymous Update

[pandoc] Allow page parameters to override site parameters.

This allows specifying things like this in the page frontmatter:

    ---
    title: Something
    bibliography:
      source: mybibliography.bib
    pandoc:
      filter:
        - make-diagrams.lua
    ...

These options are local to the page. Specifying the same under `markup`
in the site configuration applies those settings to all pages.

Paths (filters, bibliography, citation style) are resolved relative to
the page, site, and the `static` folder.

[pandoc] Support metadata

Support specifying Pandoc metadata in the site configuration and page
configuration using the following syntax:

Site (in `config.yaml`):

    ```yaml
    markup:
        pandoc:
                metadata:
                        link-citations: true
    ```

Or in frontmatter:

    ```yaml
    ---
    pandoc:
        metadata:
                link-citations: true
    ...
    ```

[pandoc] Simplify path management.

No need for any fancy path lookup gymnastics. `pandoc`'s
`--resource-path` option does the legwork of locating resources on
multiple directories.

[pandoc] Don't use x != "" to denote failure.
