Improve Client Integration

Halcyon Clients integrate awkwardly, particularly for well defined client objects like ORM models like ActiveRecord.

A reasonable and sexy solution to including functionality into objects like ActiveRecord models should be available.

For example, a possible solution could include the following code producing the expected results:

class User < ActiveRecord::Base
  include Halcyon::Client::Integrations('http://localhost:5457')
  def self.authenticate(user,pass)
    instance_eval do
      post("/user/auth/#{user}", 'password'=>pass)
    end
  end
  def permit?(key)
    get("/user/permit/#{key}")
  end
end

This can be tricky for conflicting names of properties in the actual object for clients that provide custom methods (which is highly recommended to begin with).
