Local data refactor

This branch simplifies how local data is used to generate project pages. The goal is to get rid of the big monolithic JSON file and parse it out into individual project templates, making it easier to manage changes to local data, and enable future features like generating prev/next links on project pages and templates that vary from project to project.   

* Creates individual templates for each project. 
* Refactors work.json local data, parsing out all the data points into localized project templates.
* Remove page proxy method from config.rb.
* Converted remaining project local data from JSON to YAML.
