Nit: Use override instead of virtual for destructors in non-base classes

Done. Also updated ComponentToolbarActionsFactory destructor to be virtual.

+
+  // ComponentToolbarActionsFactory:
+  ScopedVector<ToolbarActionViewController>
+      GetComponentToolbarActions(Browser* browser) override;
+
+  const ActionIdList action_ids() const { return action_ids_; }
+
+ private:
+  // A set of all action ids of created actions.

Nit: This type isn't actually a set, so don't use the word "set".

[apacible, 2015/08/10 22:38:11]

Done.
