Update argument keys for pifr 2.3

From pifr_server.install:

$map = array(
  'directory' => 'test.directory',
  'files' => 'test.files',
  'core' => 'drupal.core.version',
  'core-url' => 'drupal.core.url',
  'modules' => 'drupal.modules',
  'pifr_coder.annotate' => 'coder.annotate',
  'tests' => 'simpletest.tests',
  'clone-db' => 'simpletest.db',
  'clone-db-user' => 'drupal.user',
  'clone-db-pass' => 'drupal.pass',
);

Should be all code inside pift_cron_queue_batch_build() (pift.cron.inc) and related.
