New rails 2.1

For the fans of programming here version 2,1 of this splendid one framework that it answers to the name of ruby on rails.  This version of rails is the result of 6 months of collaboration with sviluppatori of all the world, that it has produced more than 1600 patches, a truly considerable number.
