This commit is big because anything small breaks the code. - Django dispatcher is based on regular expressions and does not need a tree structure - Reduces a lot of unnecessary dependencies among modules - Use Django sessions middlewear instead of CherryPy sessions - Introduce dependency based modules instead of numeric load order - Remove PagePlugin and simply use Django views - Eliminate page rendering wrappers in favor of Django context processors - Use custom auth for now until replaced by Django auth middlewear - Use Django templated 404 and 500 error pages
