Sunil Mohan Adapa 58d13e3ed8 Use Django dispatcher instead of CherryPy dispatcher
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
