config/routes.rb for redmine stable-1.4

[neffets]

this re-activates the formerly magic routes see: http://www.redmine.org/projects/redmine/wiki/Plugin_Tutorial#Generating-a-controller

(Starting from 1.4.0, Redmine won't provide anymore the default wildcard route (':controller/:action/:id'). Plugins will have to declare the routes they need in their proper config/routes.rb file.)
