Remove delegation to ActionController::Base

This reverts commit d7f7f5ee.

Reason: That isn't redundant IMO.

Add ActionView own logger

Fix warning: assigned but unused variable - result

Refactor FormBuilder arguments and default config

* Do not reopen AV::Base to define default form builder
  Inside the load hook we are already in AV::Base context.

* Do not pass the given block to the form builder
  The block is evaluated in fields_for context using capture, with the
  builder as argument. This means we do not need to give the block to the
  FormBuilder itself.

Refactor form_for and form_tag

ActionView content_tag_for refactoring and improvements

Silent Sprockets logger when config.assets.logger is set to false

Refactor TaggedLogging

The Post class is created everywhere in the test suite, and due to that
when applying the Array() logic to refactor content_tag_for, some other
change to the Post class was breaking record tag tests.

The solution is to rename the class to not collide with others
already defined in the test suite.

Only check for options and prefix arguments order once when running
content_tag_for with a collection.
