Improve Herald personal/global UI/UX

Summary:
  - Default "personal" vs "global" choice to "personal".
  - Don't show global rules under "My Rules".
  - After editing or creating a global rule, redirect back to global rule list.
  - Use radio buttons for "personal" vs "global" and add captions explaining the
difference.
  - For "global" rules, don't show the owner/author in the rule detail view --
they effectively have no owner (see also D1387).
  - For "global" rules, don't show the owner/author in the rule list view, as
above.
  - For admin views, show rule type (global vs personal).

Test Plan:
  - Created and edited new global and personal rules.
  - Viewed "my", "global" and "admin" views.
