updating link_to and button_to to support :remote => true and other options such as :confirm in a unobtrusive manor
Signed-off-by: NJoshua Peek <josh@joshpeek.com>

This reverts commit 3aa1ea1a, reversing
changes made to 2c12a713.

Conflicts:

	actionpack/lib/action_view/helpers/javascript_helper.rb
	actionpack/lib/action_view/helpers/url_helper.rb
	actionpack/test/template/url_helper_test.rb

making non remote versions of link_to, button_to, submit_tag and image_submit_tag output data attributes for things like :confirm, :method, :popup, and :disable_with

This allows the following setup to work:

  # app/controllers/application_controller.rb
  class ApplicationController
    def default_url_options(options=nil)
      { :locale => I18n.locale }
    end
  end

  # From your views and controllers:
  I18n.locale                 #=> :en
  users_url                   #=> "/en/users"
  users_url(:pl)              #=> "/pl/users"
  user_url(1)                 #=> "/en/users/1"
  user_url(:pl, 1)            #=> "/pl/users/1"
  user_url(1, :locale => :pl) #=> "/pl/users/1"

If you provide all expected parameters, it still works as previously.
But if any parameter is missing, it tries to assign all possible ones
with the hash returned in default_url_options or the one passed straight
to the named route method.

Beware that default_url_options in ApplicationController is not shared
with ActionMailer, so you are required to always give the locale in your
email views.

ActionView::Helpers::UrlHelper#url_for used to escape the URLs it generated by
default.  This was most commonly seen when generating a path with multiple
query parameters, e.g.

  url_for(:controller => :foo, :action => :bar, :this => 123, :that => 456)

would return

  http://example.com/foo/bar?that=456&this=123

escaping an ampersand that shouldn't be escaped.  This is both wrong and
inconsistent with the behavior of ActionController#url_for, and is changed.

  This consists of:

  * String#html_safe! a method to mark a string as 'safe'
  * ActionView::SafeBuffer a string subclass which escapes anything unsafe which is concatenated to it
  * Calls to String#html_safe! throughout the rails helpers
  * a 'raw' helper which lets you concatenate trusted HTML from non-safety-aware sources (e.g. presantized strings in the DB)
  * New ERB implementation based on erubis which uses a SafeBuffer instead of a String

Hat tip to Django for the inspiration.

  * Dependencies added
  * A few tests modified to avoid depending on AS deps
