The attached patch adds an indication to the admin/info page whether all database migrations have been run or not.

Some users forget to run the rake task @db:migrate@ when they update Redmine and encounter errors. Sometimes it is difficult for users new to Ruby on Rails to identify that the cause is that database migrations have not been run (examples: message#56635, message#62323).

The new indication that the patch introduces gives such users a chance to know the cause. It is also useful for people who are asked help from such users to figure out the cause.
