Don't break Haml with textarea newline fix. (master)

See issue #393, issue #4000, issue #5190, and issue #5191. Adds a newline after the textarea opening tag based on @codykrieger's original patch so that we don't cause regressions in Haml-using apps. The regression caused textarea tags to add newlines to the field unintentionally (each update/save added an extra newline.)

Also fix 6 more tests that didn't yet have the newline expectation.

if you want to read the file you may need to ask if there is something
to read from

    $ rails generate migration remove_foo_from_bars foo:string

This currently generates:

      def up
        remove_column :bars, :foo
          end

Fix it:

      def up
        remove_column :bars, :foo
      end

This reverts commit 7feec40b.

Reason: The guide had the contents of railties/bin/rails and I don't see
any reason to change it.

removed unused variables

objectify_options method should be applied to the proper options arg.

See explanation and example of the bug - https://github.com/kryzhovnik/rails_field_error_proc_bug_example

Previously `rendered_format` was set only based on mime types
passed in Accept header, which was wrong if first type from
Accept was different than rendered partial. The fix is to simply
move setting rendered_format to the place where template
is available and grab format from the template. If it fails
we can fallback to formats passed by Accept header.

prevent returning a negative zero from number_with_precision

Remove "needless boolean casting"

When someone accidentally passes a string to sanitize like:

sanitize("<span>foo</span>", :tags => "b")

there is no indication that it's the wrong way and span
will not be removed.

Issue with schema dump
