clogger 0.8.0 - delegating away!

Clogger now delegates all unknown methods to the response body
in cases where it needs to wrap the response body.  This allows
apps that use non-standard Rack extensions to continue working.

Eric Wong (4):
      pass along "to_io" calls to the body
      delegate method_missing calls to the response body
      pure: simpler autoload trigger
      switch to pkg.mk for maintenance tasks
