easy to read.

Fix actionview link_to with block and url_hash

When rendering recursive partial Action View is trying to generate the
view digest infinitly causing a stack level error.

Fixes #11340

Refactored strong parameters usage and updated Gemfile.lock with Rails 4

Added an `enforce_utf8` hash option for `form_tag` method

Deprecation removed build fixed

Control to output a hidden input tag with name `utf8` without monkey
patching

Before:

    form_tag
    # => '<form>..<input name="utf8" type="hidden" value="&#x2713;" />..</form>'

After:

    form_tag
    # => '<form>..<input name="utf8" type="hidden" value="&#x2713;" />..</form>'

    form_tag({}, { :enforce_utf8 => false })
    # => '<form>....</form>'

Use link_to with block and url_hash, expect block as name.
But ignore block and use url_hash as name.
3-2-stable passes this test. 4-0-stable and master fail this.

Cleanup ul_encoded_params_parsing_test

Cleanup on getting_started tutorial

Some performance benchmarking for take vs limit

Replaced <br /> with <br> for consistency; Added note about
singular/plural distinction (which was previously confusing to a Rails
noob); Rephrased explanation of how form is routed to controller, again
to reduce confusion; and added explanation to replace incorrect link.

Running isolated test for assertions and journey
