AbstractController::Rendering is module which defines thie api

This interface should be use when implementing renderers.

This reverts commit 6fe91ec5008838338e54ab8570f7c95ee0cdd8e8.

Since all rendering stuff was extracted to AV, the only thing that left was single class with error so file name wasn't relevant anymore

It's already included in Layouts, makes no sense to doubly include it

Name was singular, should be plural

This reverts commit 77bb03df2ca3687b290e9fe77d21007642f0329c.

Skip tests using deprecated +proper_table_name+ method.

This prevents deprecation warnings from popping up.

Deprecating passing strings as class name in fixtures.

Making proper_table_name take in options.

Show exceptions in text format for xhr requests

Docs: fix typo in file path, should include extension. [ci skip]

remove not used instance variable

Add a note about edge guides in the feedback section [ci skip]

The options will specify the prefix and the suffix. Also, I'm moving the
method to be an instance method on the +Migration+ instance. This makes more
sense than being a class method on the +Migrator+ class because the only
place that uses it is on a +Migration+ instance (in a method_missing
hook). The logic for the Migrator shouldn't be doing any work to
calculate the table name, it should be the Migration itself.

Also made some small indentation fixes.

Performance regression in AR::Base.respond_to?

[PG adapter] Use infinity const

Add examples of AR order method's hash notation to Rails Guide [ci skip]
