deleting more old code
Start writing tests for the new API

Rename setup() method to _setup() on DS.Model
It is pretty common to find a DB column named 'setup'.
Previously I would do something like this to map around the problem.
App.Adapter.map('App.SomeModel', {
    // setup is reserved, so we have to map around it.
    _setup: { key: 'setup' }
});
Merged master & resolved conflicts
