Slot nesting fails when nest level is greater than 2

[dordille]

The blog plugin allows you to do some pretty funky things with slots. One of these is including slots within slots. However when you include a slot in a slot in a slot things no longer work. Even worse there are 500 errors. It seems like when the slot nesting depth is greater than 2 aTools::getCurrentPage() returns the page corresponding to the slug of the virtual page used for one of the slots.

This isn't strictly a blog bug as this seems to apply to all slots nesting other slots.

The "major" part of this bug is figuring out whether we implement it or just document that you shouldn't do it and teach the code to throw an exception if you try.

The "minor" part would be actually making it work, unless we have a seriously compelling client-project-gotta-have-it reason to nest slots deeper than 2.

That said, if the implementation is stupid simple, it might be best to implement it, so I should at least look at it.

You actually can have a normal view with a_slot calls now, we resolved a lot of issues there. Of course you should not put blog slots in a blog slot template, infinite recursion is a bug in the universe (:
