Split `app/templates` into its own tree.

Currently, we are processing the entire `app/templates` and `app/styles`
directories for all `preprocessJs` filters (this means things like
`ES3SafeFilter` are actually checking each template).

This makes `templates` it's own tree, and splits things up
appropriately.

Default to development asset.
Allow vendor files to be easily configurable.

This allows alternate paths to be specified, or completely removed.

For example to exclude jQuery from the generated `vendor.js` file:

```javascript
var app = new EmberApp({
  vendorFiles: {
    'jquery.js': null
  }
});
```

This is a precursor to the new configuration syntax that will could
something like `app.config('vendorFiles', 'ember.js', <options here>)`.
