This fixes:

* Boolean with inverted logic
* Integer with inverted logic
* BigDecimal with inverted logic

Fixes #3995

closes #3341

In the current router DSL, using the +match+ DSL
method will match all verbs for the path to the
specified endpoint.

In the vast majority of cases, people are
currently using +match+ when they actually mean
+get+. This introduces security implications.

This commit disallows calling +match+ without
an HTTP verb constraint by default. To explicitly
match all verbs, this commit also adds a
:via => :all option to +match+.

Closes #5964

Commit 56089ca9 introduced a backward
incompatible change by changing the method signature of the FormBuilder.
This brings back the same method signature warning in case someone gives
a block to the builder.

Fixes #5324 by removing default size options from input:text and default cols and rows options from textarea.

Closes #393

variables in the form builder

uses PATCH for the forms of persisted records, and routes PATCH and PUT to the update action of resources

PATCH is the correct HTML verb to map to the #update action. The
semantics for PATCH allows for partial updates, whereas PUT requires a
complete replacement.

Changes:
* adds config.default_method_for_update you can set to :patch
* optionally use PATCH instead of PUT in resource routes and forms
* adds the #patch verb to routes to detect PATCH requests
* adds #patch? to Request
* changes documentation and comments to indicate support for PATCH

This change maintains complete backwards compatibility by keeping :put
as the default for config.default_method_for_update.

When the new html5 attribute :form is given to the check_box helper, it
should be replicated to the hidden field as well. Closes #4848

Raise a better error if anyone wants to create your own ActionView::Helpers::Tags::Base child and do not implement the render method

Fixed failing tests
This reverts commit 8350ce97.

This support is near-identical to the existing submit_tag support.

Example:

    <%= form_for @post do |f| %>
      <%= f.button %>
    <% end %>

You can provide a namespace for your form to ensure uniqueness of id attributes on form elements.
The namespace attribute will be prefixed with underscore on the generate HTML id

f.number_field generates <input type="number", size="30"../> which is
invalid HTML5. See: http://dev.w3.org/html5/spec/Overview.html#number-state
