easy way to get contextualized models

[drewfish]

The current ac.models.get() takes the YUI module name as the argument. This means that I (as an app developer) need to know ahead of time which YUI module to use for a model.

The feature request is to augment ac.models.get() to take the model name (for example, foo for models/foo.server.js) and to use the correct model for the current context.

As it turns out, the mojit resolution process already has this exact mapping. (It can be found at ac.command.instance.models.)

For backwards compatibility we should probably first look in Y.mojito.models[name] then fallback to Y.mojito.models[instance.models[name]] which implements this feature. (Plus good error checking of course.)

Sounds good to me!
