Add more basic project models and tests for loading and dealing with project data in Backbone.
 - This allows easier visualization in UIs by using Backbone views, and allows easy new project generation using model defaults.
 - TODO: Use this in builders.
Rename default project file to ezc.json instead of Cakefile.json, to match the project name.
Bring source/ directory coverage up to 100% to match builders/ and models/
Add some command line options for using ezc (release, template, environment)
