allow specifying generic lists of files for use in templates

[maks]

Tota looks great! and I would love to move over to tota for my current static site, but the current minimal JS based static site gen I currentl use has the concept of specifying lists in its (json based) config, eg.

"lists": {
    "projects": {
      "filter": "file.path = projects/p/*",
      "sort": "display-order ASC"
    },
    "talks": {
      "filter": "file.path = talks/items/*",
      "sort"   : "file.modified DESC"
    }
  }

which I can then make use of in moustache template partials like so:

 {{#talks}}                 
      <li>
       {{#url}}
        <video class="img-responsive talk-video-asset" width="320" height="240" controls >
          <source src=" {{{ url }}}">
        </video>
        {{/url}}

       <div class="caption">
          <strong>{{ title }}</strong> 
            <p>{{{ md }}}</p>
               {{#slides}}
               Slides are available <a href="{{{ slides }}}">here</a>
               {{/slides}}
               {{^slides}}
               Unfortunately the slides for this talk are not available.
               {{/slides}} 
            <p/>
          </div>
       </li>
{{/talks}}

So this would be somewhat like making the current special case of posts more generic.

Would you be open to adding this to tota or accepting a contribution to add this functionality?
