  Added in credits.
  Use site's name for basic auth realm
  Make apigroupcreate.php pass phpcs
  Took out some unnecessary intializations
  Implemented create group api

  These same params are used in most API actions; moved to base API class
  Missed some of the references to the old TwitterApiAction - removed
  Remove more redundant $formats
  Remove dead code
  Move all basic auth output and processing to base classes
  $format is used by every API action. Set it in the base class.
  Delete action/api.php and rename lib/twitterapi.php to lib/api.php
  New actions for blocks via API
  fix FBConnect so it doesn't muffle EndPrimaryNav
  don't write session if it's unchanged
  Fixed facebook connect primary nav to hide search option when site is private and user is not logged in
  Fixed facebook connect primary nav to obey sms/twitter/openid settings
  Fixed facebook connect login nav to obey openid settings
  Fixed facebook connect nav to obey sms/twitter disabled
