[katello-devel] Rails 3.2 features

[Eric D Helms]

My previous experience porting a 3.0 app to a 3.2 application wasn't too
shabby in the end.  I only had to change application.rb and the rest was
all asset pipeline related which just involved mostly moving files around
and creating manifests for the Javacript files.
