Generic Provider to access entries

[beberlei]

To print summary pages, rss feeds and such i feel the need to access all the data from the other views in a template.

For example:

{% for entry in site.entries %}

This is of limited use though, as i need them sorted by a FM variable:

{% for entry in site.entries.sort("fm_varname", "DESC") %}

Maybe a twig filter/function can do this.
