Action Controller::RoutingError on redmine 2.x

First, thanks for this simple, yet quite useful plugin.

So on a fresh install, plugin migration occurs without failures, but when I enable the module on a project, any access to this project fails with:

ActionController::RoutingError (No route matches {:project_id=>#<Project id: 37, name: "DFD Programer", description: "", homepage: "", is_public: true, parent_id: nil, created_on: "2012-05-17 13:25:28", updated_on: "2012-05-17 13:25:28", identifier: "dfdprogramer", status: 1, lft: 1, rgt: 2, inherit_members: false>, :controller=>"treasures"}):

Many redmine plugins made prior to 1.4(I believe) have suffered from the same issue. The updated redmine tutorial (http://www.redmine.org/projects/redmine/wiki/Plugin_Tutorial#Adding-routes) mentions that routing needs to be configured in config/routes.rb. I am a programmer but I am not familiar with ruby or rails at all. Can you guess/suggest what route should be added for the plugin to work? I will fork your repo, make the changes, debug as much as I can, test it and send a merge request later.
