Moved stuff around, started build page, added filter

### Updates
- Added the beginnings of a build page
- Started to create models for data storage and for moving cache over to database
- Added ways of accessing back links and mutual links
- Added a simplistic filter to prereq finding
- Reorganized to move static files and templates into specific projects

### Goals
- Get build page functional and looking decent
- Get models working, migrate caching to the database (or maybe a different database for this specific purpose)
- Get data collection working
- Possibly move some wikipedia requesting/parsing stuff over to [pattern](http://www.clips.ua.ac.be/pages/pattern)
- **Get stuff distributed and start collecting data!**
