Massive refactoring of of the core....
Massive refactoring of of the core.
* The magic aliases now work again.
* Prefilters are components.
* Fixed a bug that was turning the displayhook off to early, which was
preventing magic and !! results from going through the displayhook.
* Refactored config system. The config system now supports config
subsections, like config.Global. These sections, which must start
with an uppercase char, are auto-created upon a getattr.
