Added cache for application settings (Setting model). Once the values are cached, only one database query is done at each user request (to check if the cache is still valid). git-svn-id: http://redmine.rubyforge.org/svn/trunk@685 e93f8b46-1217-0410-a6f0-8f06a7374b81 17 years ago			`class AddSettingsUpdatedOn < ActiveRecord::Migration`
