Fixed issue with error message not appearing

Fix due to issue #24. Because the #additives route redirects to
 #additives/category1 the 'route-found' event is triggered twice. This

 used now. This event is triggered only when content of the pane div is
 about to change.

Related to issue #24. It should be possible to go back to the category
additive list for the category that the currently viewed additive resides
in.
