kcar 0.3.1 - Kcar::Response minor bugfix

One bugfix for the optional Kcar::Response module:

* propagate EOFError on remote errors

  When proxying remote requests, EOFError may get incorrectly
  discarded when a the remote server sets the Content-Length:
  header _and_ Connection:close to disconnect the connection.

  We will now raise errors correctly when Connection:close
  is give but we have not yet read the expected Content-Length.
