Render attributes through standard template files

Created by: gracewashere

Adapter templates live in lib/adapters/views

Pass request into adapters to access URL helpers

Specifically, the polymorphic_path helper used by the BelongsToAdapter needs to access request.host in order to look up the appropriate path. There will likely be other cases where views will need to access the controller's request object.

Automatically look up templates for adapters

If you don't need any complicated logic to display an attribute, you can get away with just defining template files and a skeleton Adapter class
