This helper no longer makes sense as a separate method. Instead I'll
just have `deserialize` call `cast` by default. This led to a random
infinite loop in the `JSON` pg type, when it called `super` from
`deserialize`. Not really a great way to fix that other than not calling
super, or continuing to have the separate method, which makes the public
API differ from what we say it is.

These files get modified whenever someone uses a tool like `sed`. Let's
just get this over with in one commit so it'd not adding diff noise to
something else.

We do this in the adapter classes specifically, so the types aren't
registered if we don't use that adapter. Constants under the PostgreSQL
namespace for example are never loaded if we're using mysql.

As per previous discussions, we want to give users the ability to
reference their own types with symbols, instead of having to pass the
object manually. This adds the class that will be used to do so.

Implement http_cache_forever to ActionController

Add http_cache_forever to ActionController, so we can cache results
forever.
Things like static pages are a good candidate for this type of caching.

This cache only controls caching headers, so it is up to the browser to
cache those requests.
