* Camping.use injects a Rack middleware.
* Update Flipbook to RDoc 2.4

* Camping::Session now uses session-cookies. The AR-backend is gone for now.
* camping/db.rb has been renamed to camping/ar.rb.
* Camping now uses Rack internally. Every app responds to #call.

= 1.6
=== Never released

* Camping::Apps removed, it wasn't reliable.
* bin/camping server kinds splitted in various files.
* NotFound and ServerError controllers changed to methods :

  r404 : called when a controller was not found
  r500 : called on uncaught exception
  r501 : called on undefined method

  All of those can be overridden at your taste.

* Markaby no longer required. Like AR, is it autoloaded on (Mab) usage.
* Camping::H is now inheriting from Hash instead of HashWithIndifferentAccess.
* Which made possible to remove the last strict dependency : active_support
* #errors_for removed, it wasn't really used
* Bug fixes !
