Improve custom configuration

1. Hashes can be assigned
2. We don't need a special level anymore

The method chain only works in the top level.

If users need a second level they need to assign a OrderedOptions to the
key:

    config.resque.server = ActiveSupport::OrderedOptions.new
    config.resque.server.url = "http://localhost"
    config.resque.server.port = 3000

 You can configure your own code through the Rails configuration object with custom configuration. It works like this:
 
   ```ruby
-  config.x.payment_processing.schedule = :daily
-  config.x.payment_processing.retries  = 3
-  config.x.super_debugger = true
+  config.payment_processing.schedule = :daily
+  config.payment_processing.retries  = 3
+  config.resque = { timeout: 60, inline_jobs: :always }
+  config.super_debugger = true
   ```
 
 These configuration points are then available through the configuration object:
 
   ```ruby
-  Rails.configuration.x.payment_processing.schedule # => :daily
-  Rails.configuration.x.payment_processing.retries  # => 3
-  Rails.configuration.x.super_debugger              # => true
-  Rails.configuration.x.super_debugger.not_set      # => nil
+  Rails.configuration.payment_processing.schedule # => :daily
+  Rails.configuration.payment_processing.retries  # => 3
+  Rails.configuration.resque.timeout              # => 60
+  Rails.configuration.resque.inline_jobs          # => :always
+  Rails.configuration.super_debugger              # => true
   ```
