Update to 0.4:

Released on 2013/12/07.

* Cope with the lack of AM_PROG_AR in configure.ac, which first
  appeared in Automake 1.11.2.  Fixes a problem in Ubuntu 10.04
  LTS, which appears stuck in 1.11.1.

* Stopped shipping an Atffile.  The only supported way to run the tests
  is via Kyua.

Interface changes:

* Issue 5: New methods added to the state class: open_all.

* Removed default parameter values from all state methods and all
  standalone operations.  It is often unclear what the default value is
  given that it depends on the specific Lua operation.  Being explicit
  on the caller side is clearer.

* Modified operations do_file and do_string to support passing a number
  of arguments to the loaded chunks and an error handler to the backing
  pcall call.
