Extracted redirect logic from ActionController::Force::ClassMethods.forc...

Prior to this patch the existing .force_ssl method handles both defining
the filter and handling the logic for performing the redirect.

With this patch the logic for redirecting to the HTTPS protocol is
separated from the filter logic that determines if a redirect should
occur.  By separating the two levels of behavior, an instance method
for ActionController (i.e. #force_ssl_redirect) is exposed and available
for more granular SSL enforcement.

Cleaned up indentation.

Eliminate the warnings generated by redefining methods and constants.

Add code statistics for Javascript and CoffeeScript files

Missed that too, thanks again @splattael.

Thanks @splattael.

Add some tests for link_to with blocks and escaping content.

Prefer Hash#[]= over Hash#merge when setting a value.

Remove :to_sym call from public_instance_methods iteration, as such
methods in Ruby 1.9 already return symbols. Initialize valid conditions
with controller/action instead of setting them afterwards.

Changed symbol platform to platforms for the commented out call to gem 'therubyracer'.

Dependency.rb expects the symbol to be named :platforms as opposed to platform. RubyMine's inspections indicate that the symbol should be named :platforms.

accept a block in button_to helper

Make possible to use a block in button_to helper if button text is hard
to fit into the name parameter, e.g.:

    <%= button_to [:make_happy, @user] do %>
      Make happy <strong><%= @user.name %></strong>
    <% end %>
    # => "<form method="post" action="/users/1/make_happy" class="button_to">
    #      <div>
    #        <button type="submit">
    #          Make happy <strong>Name</strong>
    #        </button>
    #      </div>
    #    </form>"
