Subject: [PATCH] actions: Don't show in the places-sidebar menu, unless
 Conditions allow it.

By default, actions will no longer appear in context menus for
places-sidebar entries.

To opt back in to sidebar visibility, two new Conditions are added:
- sidebar-allow: Display in the sidebar, along with any other valid
  locations assuming all conditions are met (consider this 'legacy'
  behavior).
- sidebar-only: The action will only be shown in the sidebar, provided
  other Conditions are met, and nowhere else. Use this for actions
  that only make sense when applied to sidebar items (bookmarks,
  mounts, etc...).
