New setting added to specify how many objects should be displayed on most paginated lists....

New setting added to specify how many objects should be displayed on most paginated lists. Default is: 25, 50, 100 (users can choose one of these values). If one value only is entered in this setting (eg. 25), the 'per page' links are not displayed (prior behaviour). git-svn-id: http://redmine.rubyforge.org/svn/trunk@1026 e93f8b46-1217-0410-a6f0-8f06a7374b81
