#290766 group admins were missing their powers when og_access disabled. reworked og_is_node_admin(). as a result, we no longer require that the group node be authored in the default input format.

Make available to javascript code the group context of a page. See Drupal.settings.og ...  Useful for adding group context info into ad tags or Google Analytics (for example).

#249902 array errors. also improve hook requirements and admin/og/og a little when no groups have been specified.

only show wiki options for a content type if og_access module is enabled. folks are now encouraged to try out the new content type selector at the bottom of the content type edit form. you can now safely designate a content type as a wiki, similar to what you may have seen on groups.drupal.org.

#157140 by moshe weitzman. major patch to let site admin specify which content types should act like a wiki (i.e. any group member may edit). See the new 'content types' fieldset on the admin/og/og page ... Requires a visit to update.php which will rebuild your node access table. I have a little code shuffling to do still so you might want to wait until next commit before trying this. Also implements #111836 which changed how we do node access grants.

#216812 by alex_b and moshe weitzman. move access control to a new og_access module. this feature isn not quite finished. please wait until my next commit and then help test this major change.
