Clean up events views: return_to, subnav, remove custom_rrule

- events_controller: wire return_to through show and new actions;
  create respects return_to with fallback to node/event path;
  new pre-populates node_id and tag_list from params
- events/edit: remove custom_rrule checkbox; node link removed from
  subnav (use show for node navigation); destroy button added
- events/new: remove custom_rrule checkbox; add return_to hidden
  field and back link; tag_list field added
- events/show: fix back link via safe_return_to; add node link to
  subnav; add destroy button; remove custom_rrule display; show
  humanized rrule below raw string
- events/index: destructive class on destroy button; node_id column
  replaced with node link; show/edit links carry return_to
- nodes/show: add show/edit links to event entries with return_to
