Issues rendering addon-scoped components with Wall St Syntax

[elwayman02]

field-guide doesn't play nicely with addon namespacing via https://github.com/rwjblue/ember-holy-futuristic-template-namespacing-batman

So if you're working in an addon (the primary use-case for field-guide), and you're not re-exporting your components in the app/ folder (which is a pretty good practice to avoid, since you could clobber components in the consuming app), you can only render components in field-guide using the component helper. That is, this will work:

{{component 'my-addon@my-component'}}

but this will not:

<MyAddon$MyComponent/>
