Initial commit for zentasks.

This is a todo example posted on the official Play website that I'll be working
on for the forseeable future. Exploring the Play MVC framework and messing
with the Java version of the APIs.
Implements base models.

Continuing to work through this example app by implementing the base
models. Also included a few tests for models. Woo!
Fleshes out Model tests

Apparently you can use YAML to describe fixture data, pretty sweet!
Refactors templates and adds styles.

Added some more structure to the todo app and included a few styles provided
by the ZenTasks tutorial.
Implemented authentication and protected routes.
Implemented project routes, something something sub-templating.
Implemented JS routes and actions.

Although, for the most part, it's not really working. I think moving forward
I'll stick to Javascript, unless I randomly find myself with oodles of time
to figure out CoffeeScript.
