Title: Adds "all" methods to Entity.

By this change, we can "get all" from datomic:

```ruby
class Person
include Diametric::Entity
include Diametric::Persistence::Peer

attribute :name, String, :index => true
attribute :birthday, DateTime
attribute :awesome, :boolean, :doc => "Is this person awesome?"
end

# detabase creation/instance creation/etc...

people = Person.all
```
