Subject: [PATCH] Corrected shipherd Navigation cache clearing and made
 grappelli attribute inline template compatible with grappelli r1399. Tweaked
 recursenavigation template tag behavior to set {{ navigation }} in the
 context instead of node and corrected its documentation. Added has_navigation
 filter.
