Title: replace ruby-debug19 with debugger on Rails 3-2 stable

In continuance of #5835 , an appropriate patch to weed out ruby-debug19 from Rails-3-2 master as well. It is likely a large number of people are going to generate new Rails 3.2 apps on ruby1.9.3 for sometime in the future. The guidance should be to use the debugger gem on that platform.
