[WIP] Lists with all records in a multiple-section

[cctuan]

Proposal

Add innersection and excludeself parameter for section type template.

When Vapid user would like to display relative sections in one of sections,

ASIS.
_sections.html

{{#section sections}}
  {{section_name}}
  {{section_description}}
  <h3>Relative Links</h3>
  <ul>
  {{#section sections}}
     <li>{{section_name}}</li>
  {{/section}}
  </ul>
{{/section}}

The above template will only display one section information in Relative Links.

  <h3>Relative Links</h3>
  <ul>
  {{#section sections innersection=true}}
     <li>{{section_name}}</li>
  {{/section}}
  </ul>
{{/section}}

The above template will only display ALL section information in Relative Links.
