Improve drafts & status system

Improve drafts & status system.

[mhoennig]

I'm working on this because the current draft system is really unsable. See also issue 652.

My personal requirements:

• draft posts should be rendered with '-draft' added, as it's now, is fine
• but there should be no links from non-draft pages to draft-posts
• also prev/next should never point to draft-posts, maybe except if the page is a draft itself
• draft articles should not count for the tag-counters
• I would like to have a page drafts.html similar to archive.html which contains all drafts
• I want to be able to add password protection to all draft-related pages via .htaccess/.htpasswd

Most of these requirements I've already implemented in my local version, but it's not production ready yet and unit tests need to be improved.

What would be your requirements?

There should also be a usable way to iterate over published content of [type] (currently, there are only collections of all content of type, which could in theory be filter, but must take into account the possible values of status (draft, published and also published-date).
Don't forget to consider the status "published-date" in all of the requirements. It would probably make sense to add a boolean field "published" to the content data model.

Happy to receive any pull requests related to the above 👍

An additional two:

• draft.prefix=[prefix]
  -- prefix could include paths
  -- path could be relative to content or begin with slash, a la .gitignore, to be off server root
• render.drafts=[boolean]
  -- true (default, as it is now)
  -- false (do not include any drafts in output)
