WIP
Update both ember and ember-data to master HEAD.
Update to grunt 0.4.x, as well as other packages.
Fix test, remove underscore.
Precompile util functions. Woo. No syntax errors in browser for now.
Update ember and ember data.
Fix gruntfile, update ember data version in our app.
Use property objects instead of arrays.
Use ember_templates instead of grunt-contrib-handlebars.
Use regular hasMany/belongsTo and skip the complex stuff for now.
WIP, working on mostly the frontend Ember.js code.
