Test that we can find the latest_change for an article

That is, the date of the most recent comment on the post.
A method to find the latest change for a post
Remove helpers that will get replaced with XDeadly::{Article,Comment}
Test that we have a subject shortcut
Add a Post shortcut to the Subject header
Tests for stringification of posts and the new bool context

I am not sure that is actually how we want to treat it as bool.
Perhaps a better bool overload will come to me later.
Overload Post stringification

Because we often want to use "/article/$article" to link to a story.
Tests for post moderation
Add a module for moderation of posts

Because that is apparently necessary.
Test that we a post can ->mod and it isa( XDeadly::PostMod )
Add an attribute to find the moderation for this post

Because we needs it.
Test more shortcuts for common headers
Easy accessors for common headers

Because we need them
Use XDeadly::{Article,Comment} because we'll need them
Add back some simpler helpers that do things we need

Quite a few annoying ones.  Not sure about testing them, so for now, just
making sure the different pages load.
Update some routes with new helpers and story formats

Specifically, now a story is an object, not a hash.  That does make
it work a bit less easily for the templates, but overall much nicer.
Use the Config plugin so we can modify the config for testing
merge
Tests for the summary feeds

Fairly basic, but show that it works.
Fix the summary json and rss

Becase it needed updating too.
