Running Halcyon With No Server

Essentially, make it work so that Halcyon applications can be run without Rack and not in an explicit Halcyon app-space.

This may be connected to the issue with making a Flat Halcyon app file.

Example of running Halcyon without Rack:

require 'halcyon'
require 'rack/mock'
class Application < Halcyon::Controller
  def time
    ok(Time.now.to_s)
  end
end
class Halcyon::Application
  route do |r|
    r.match('/time').to(:controller => 'application', :action => 'time')
  end
end
@log = ''
Halcyon.config = {'log_level' => 'debug', 'logger' => Logger.new(StringIO.new(@log)), 'allow_from' => 'all'}.to_mash
@app = Halcyon::Runner.new

Then you can use the Rack request mocking class to request actions:

@app.call(Rack::MockRequest.env_for('/time'))

or even

Rack::MockRequest.new(@app).get("/time")

Note: this was my way of documenting various ways to debug and test (especially for the specs I'm working on) Halcyon apps without requiring servers and for allowing step-through capability. This may be wrapped up into a command like init and start to allow for interactive mode or something.
