Prior to Rails 2.3.x ApplicationController was in application.rb, it is now application_controller.rb

This patch also will allow railroad to correctly recognize STI models.
Also,  updated ChangeLog file.

Hi Juris,

blindly replacing "application.rb" with
"application_controller.rb" would break Railroad on
Rails < 2.3.

What about deciding which file name to use by looking at the
return value of the `Rails.version` helper?

Something like this:

files << 'app/controllers/application.rb' if Rails.version.to_f
< 2.3

in the third hunk of your patch (controllers_diagram.rb:23);
without adding explicitly for Rails >= 2.3, because the previous
Dir.glob would already put the file into the array ;), and:

require 'app/controllers/application' + ('_controller' if
Rails.version.to_f >= 2.3).to_s + '.rb'

in the fourth one (same file, line 39)

What do you think? Care to provide an updated patch? :)

Thanks!

~Marcello
