Add clubs utility template tags
Merge branch 'develop' into utility-tags
Created utility template filters for clubs permission checks
Configured the show activity page to use permission filters instead of "can_do_so_and_so" context items passed from the view
 This increases independence of the template from the views that uses it
Added missing active_tab context item

Activity.is_approved is now (returned to be) set to False whenever
