Handle sanitize_options in simple_format helper

[faraquet]

Motivation / Background

We needed to open the links in a new window along with the simple_format from ActionView already used on the project. The problem is that Rails removes target="_blank" by default.

This pull request is based on @Rubyist007 solution.

[1] pry(main)> simple_format("<a target=\"_blank\" href=\"http://example.com\">Continue</a>")
=> "<p><a href=\"http://example.com\">Continue</a></p>"

I noticed that simple_format uses sanitize, but doesn't allow options for this, however, adding the extra sanitize options such as attributes: %w[target href] will resolve my issue.

rails/actionview/lib/action_view/helpers/text_helper.rb

Line 321 in fa77687

text = sanitize(text) if options.fetch(:sanitize, true)
