Previously, access control to group tabs was handled in two ways: - for BP_Group_Extension tabs, the 'enable_nav_item' and 'visibility' provided some control over access to plugin developers, though it was inconsistent, buggy, and difficult to implement properly - for tabs provided by bp-groups, access to the tabs of non-public groups was controlled directly in the BP_Groups_Component::setup_globals() method Aside from being unclear for developers, this technique for controlling access was also inflexible. For non-public groups, tab access was hardcoded and handled before BP_Group_Extension plugins even had a chance to load. As a result, it was essentially impossible to add public tabs to non-public groups (among other non-standard customizations). The current changeset comprises a number of changes that make tab access more consistent and flexible: - Access control is moved to the new bp_groups_group_access_protection() function. This function has the necessary filters to customize access protection in arbitrary ways. And because it loads at 'bp_actions' - just before the page begins to render - all extensions have had a chance to load and register themselves with the desired access settings. - The 'visibility' and 'enable_nav_item' properties of BP_Group_Extension are phased out in favor of 'access' and 'show_tab' params. 'access' controls who can visit the tab, while 'show_tab' controls who can see the item in the navigation. These new properties have intelligent defaults (based on the privacy level of the group), but can be overridden with a number of custom settings: 'admin', 'mod', 'member', 'loggedin', 'anyone', or 'noone'. Backward compatibility is maintained, so that existing BP_Group_Extension plugins that use enable_nav_item or visibility will continue to work as before.
