Misc #21209: Endless classes and modules

----------------------------------------
Endless methods have proven popular enough that we should bring the same en=
dlessness to module/class definitions.

For a long time we've had this ugly pattern of class definitions with an ex=
treme level of indentation.

I propose a simple new rule to fix this: if a 'class' or 'module' statement=
 is at the beginning of a line, the matching 'end' becomes optional; EOF is=
 enough.

instead of:
```ruby
module Arel
  module Visitors
    class UnsupportedVisitError
      module ClassMethod
        module AmIDeepEnough
          module NoNotDeepEnough
            class LetsGoDeepter
=20
              def firstmethod
                "man, I'm just the first method and already indented 14 spa=
ces deep!"
              end
             =20
            end #what
          end #a=20
        end #chain
      end #we
    end #have
  end #here
end #weee!!!
```

we can have the much more readable:
```ruby
module Arel
module Visitors
class UnsupportedVisitError
module ClassMethod
module AmIDeepEnough
module NoNotDeepEnough
class LetsGoDeepter

def firstmethod
  "now that's better!"
end
```

Brilliant!
