Removed all newInstance() methods, refs #154
Started work on Model support rewrite, refs #151
Improved config handlers and removed class elements, refs #124 and #123
Some Context/Controller cleanup, moved ActionStack, refs #153
Added folder for xsd files, refs #123
All classes defined in factories.xml can take parameters now, or at least
most of them.
Tons of other stuff. I should do checkins more frequently, and work on one
thing at a time instead of ten things in parallel :)
