Zach Copley e071a8cbff Moved group create API into its own action 
Merge branch '0.9.x' into refactor-api

* 0.9.x:
  Implemented create group 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
  Fixed twitter defaulting to disabled
  Revert "Open tags should have closing tags"
  Don't show search suggestions for private sites
  Fixed E_NOTICE when returnto isn't set
  Fixed E_NOTICE when the "lite" parameter isn't included in the request
  Fixed E_NOTICE - GroupList expects an owner object in the constructor, not an array of search terms
  Returning false seems to fix IE from reclaiming window focus. I think
  Aligning notice attach label from right instead of left
  Fixed IE background image alignment for attach, favour and disfavour
  Fixed nudge and direct message background image alignment
  Using 'CSS sprites' for common icons for the identica theme. Default
  Open tags should have closing tags
