Add a way to view all saved queries
My users are trying to create and save queries and they're having a hard time making them to be shared with others, and I can't easily help because I have no way to see all the saved queries in the system. I can see one at a time by changing the number in the URL "redmine/queries/123/edit/" but the seemingly obvious "redmine/queries/" doesn't give me a list of all of them. The list should also show if the query is public or private. This should be an admin only feature.
